+* Small but important fixes needed in existing features:
-* Bring back the feature of showing the part of the buffer that is a problem
- for the use of the preferred coding systems.
+** Fix the kill/yank treatment of invisible text. At the moment,
+ invisible text is placed in the kill-ring, so that the contents of
+ the ring may not correspond to the text as displayed to the user. It
+ ought to be possible to omit text which is invisible (due to a
+ text-property, overlay, or selective display) from the kill-ring.
-* Make compile.el record the markers that point to error loci
- on text properties in the error message lines.
+** battery.el display-battery should be replaced with a minor mode.
-Important features:
+** Redefine define-generic-mode as a macro, so the compiler
+ sees the definitions it generates.
-* Provide user-friendly ways to list all available font families,
- display a font as a sample, etc.
+** Change the way define-minor-mode handles autoloading.
+ It should not generate :require. Or :require in defcustom
+ should not be recorded in the user's custom-set-variables call.
-* Program Enriched mode to read and save in RTF. [Is there actually a
- decent single definition of RTF?]
+** The buttons at the top of a custom buffer should not omit
+ variables whose values are currently hidden.
-* Implement something better than the current Refill mode. This
+* Important features:
+
+** Provide user-friendly ways to list all available font families,
+ display a font as a sample, etc. [fx is looking at multilingual
+ font selection for Emacs 23.]
+
+** Program Enriched mode to read and save in RTF. [Is there actually a
+ decent single definition of RTF? Maybe see info at
+ http://latex2rtf.sourceforge.net/.]
+
+** Implement something better than the current Refill mode. This
probably needs some primitive support.
-* Implement primitive and higher-level functions to allow filling
+** Implement primitive and higher-level functions to allow filling
properly with variable-pitch faces.
-* Implement a smoother vertical scroll facility, one that allows
- C-v to scroll through a tall image.
+** Implement a smoother vertical scroll facility, one that allows
+ C-v to scroll through a tall image. The primitive operations
+ posn-at-point and posn-at-x-y should now make it doable in elisp.
+
+** Implement intelligent search/replace, going beyond query-replace
+ (see http://graphics.csail.mit.edu/~rcm/chi04.pdf).
-* Implement other text formatting properties.
-** Footnotes that can appear either in place or at the end of the page.
-** text property that says "don't break line in middle of this".
+** Implement other text formatting properties.
+*** Footnotes that can appear either in place or at the end of the page.
+*** text property that says "don't break line in middle of this".
Don't break the line between two characters that have the
same value of this property.
-** Discretionary hyphens that are not visible when they are at end of line.
+*** Discretionary hyphens that are not visible when they are at end of line.
-* Make movemail work with IMAP.
+** Make movemail work with IMAP.
-* Internationalize Emacs's messages.
+** Internationalize Emacs's messages. [Note that this is of limited
+ use until the menus can display multilingual text. It also doesn't
+ address important issues like using the names of symbols essentially
+ as documentation, e.g. in command names and Custom. -- fx]
-* Port Emacs to GTK+. (Relevant work has been done already.)
+** Make the Lucid menu widget display multilingual text. [This
+ probably needs to be done from actual Emacs buffers, either directly
+ in the menu or by rendering in an unmapped window and copying the
+ pixels. Note that the relevant Xlib functions assume a specific
+ locale; that isn't good enough even if X can render the arbitrary
+ text, which it often can't as far as I can tell. -- fx] [The gtk
+ port now displays multilingual text in menus, but only insofar as
+ Emacs can encode it as utf-8 and gtk can display the result.]
-* Make the Lucid menu widget display multilingual text.
-
-* Remove the limitation that window and frame widths and heights can
+** Remove the limitation that window and frame widths and heights can
be only full columns/lines.
-* Move fringe to be displayed between display margins and text area.
- [KFS is looking into this].
+* Other features we would like:
+
+** A function to check for customizable options that have been
+ set but not saved, and ask the user whether to save them.
+ This could go in kill-emacs-query-functions, to remind people
+ to save their changes. If the user says yes, show them
+ in a Custom buffer using customize-customized.
-* Set fringe widths per-window/per-buffer.
+** ange-ftp
+*** understand sftp
+*** Use MLS for ange-ftp-insert-directory if a list of files is specified.
-* Make fringe bitmaps user configurable. Maybe add ability to add
- additional bitmaps to the fringe from lisp.
+** Ability to map a key, including all modified-combinations.
+ E.g map mouse-4 to wheel-up as well as M-mouse-4 -> M-wheel-up
+ M-C-mouse-4 -> M-C-wheel-up, H-S-C-M-s-double-mouse-4 ->
+ H-S-C-M-s-double-wheel-up, ...
-Other features we would like:
+** Beefed-up syntax-tables.
+*** recognize multi-character syntactic entities like `begin' and `end'.
+*** nested string-delimiters (for Postscript's (foo(bar)baz) strings).
+*** support for infix operators (with precedence).
+*** support for the $ (paired delimiter) in parse-partial-sexp.
+*** support for hook-chars whose effect on the parsing-state is specified
+ by elisp code. Thus a char could both close a string and open a comment
+ at the same time and do it in a context-sensitive way.
+*** ability to add mode-specific data to the partial-parse-state.
-* Have a command suggestion help system that recognizes patterns
+** Add a way to convert a keyboard macro to equivalent Lisp code.
+
+** Have a command suggestion help system that recognizes patterns
of commands which could be replaced with a simpler common command.
It should not make more than one suggestion per 10 minutes.
-* Add a way to define input methods by computing them (when first used)
+** Add a way to define input methods by computing them (when first used)
from other input methods. Then redefine C-x 8 to use a
user-selected input method, with the default being the union of
latin-1-prefix and latin-1-postfix.
-* Implement a clean way to use different major modes for
- different parts of a buffer.
+** Implement a clean way to use different major modes for
+ different parts of a buffer. This could be useful in editing
+ Bison input files, for instance, or other kinds of text
+ where one language is embedded in another language.

output to a different filter.

-* Replace finder.el with something that generates an Info file

-* Save undo information in files, and reload it when needed
- for undoing.
+** Implement a variant of uncompress.el or jka-compr.el that works with

-* Merge the Emacs regex.c with the Glibc regex.c.
- They split off a few years ago through negligance.
+** Save undo information in special temporary files, and reload it
+ when needed for undoing. This could extend undo capacity.

+ compiled and don't warn about functions defined in them.
+
+** Highlight rectangles (`mouse-track-rectangle-p' in XEmacs). Already in CUA,
but it's a valuable feature worth making more general.

-* Eliminate the storm of warnings concerning char/unsigned char

mismatches that we get with proprietary compilers on various systems.
They make it difficult to spot the important warnings.

-* Investigate using GNU Lightning or similar system for incremental

is displayable (particularly needed in XFree 4, sigh). Use it to
define useful glyphs that may be displayed as images or unicodes
(with ASCIIfied fallback via latin1-disp). Examples include

-* Convenient access to the `values' variable. It would be nice to have an
+** Convert the XPM bitmaps to PPM, replace the PBMs with them and scrap
+ the XPMs so that the colour versions work generally. (Requires care
+ with the colour used for the transparent regions.)
+
+** Convenient access to the `values' variable. It would be nice to have an
interface that would show you the printed reps of the elements of the
list in a menu, let you select one of the values, and put it into some
other variable, without changing the value of `values'.
+
+** (Controlled by a flag) make open and close syntax match exactly,
+ i.e. `(' doesn't match `]'.
+
+** Specify parameter ID-FORMAT in all calls to `file-attributes' and
+ `directory-files-and-attributes' where attributes UID or GID are used.
+ Whenever possible, use value 'string.
+ When done, change meaning of default value from 'integer to 'string.
+ If value 'integer is used nowhere, remove the parameter ID-FORMAT from
+ the definition of `file-attributes' and `directory-files-and-attributes'
+ and from the calls.
+
+** Make language-info-alist customizable. Currently a user can customize
+ only the variable `current-language-environment'.
+
+** Improve language environment handling so that Emacs can fit
+ better to a users locale. Currently Emacs uses utf-8 language
+ environment for all utf-8 locales, thus a user in ja_JP.UTF-8 locale
+ are also put in utf-8 lang. env. In such a case, it is
+ better to use Japanese lang. env. but prefer utf-8 coding system.
+
+** Eliminate the current restriction on header printing by ps-print.
+ Currently, a header can contain only single 1-byte charset in
+ addition to ASCII.
+
+** In ps-print, provide an user friendly interface to specify fonts.
+
+** OpenType font support for various complex scripts (e.g. Devanagari).
+ As X protocal doesn't provide a way to access OpenType Layout Tables
+ in a OpenType font of a server side, we need a way to utilize local
+ fonts (perhaps by directly using the Freetype library or indirectly
+ via Xft library).
+
+** Enhance word boundary detection for such a script that doesn't use
+ space at word boundary (e.g. Thai).
+
+** Implement interface programs with major Japanese conversion server
+ in lib-src so that they can be used from the input method
+ "japanese". Currently, most Japanese users are using external
+ packages (e.g. tamago, anthy) or an input method via XIM.
+
+** Provide the toolbar on ttys. This could map a bit like tmm-menubar
+ for the menubar and buttons could look a bit like those used by customize.
+
+* Internal changes
+
+** Replace gmalloc.c with the modified Doug Lea code from the current
+ GNU libc so that the special mmapping of buffers can be removed --
+ that apparently loses under Solaris, at least. [fx has mostly done
+ this.]
+
+** Rewrite make-docfile to be clean and maintainable.
+
+** Add an inferior-comint-minor-mode to capture the common set of operations
+ offered by major modes that offer an associated inferior
+ comint-derived mode. I.e. basically make cmuscheme.el/inf-lisp.el generic.
+ For use by sml-mode, python-mode, tex-mode, scheme-mode, lisp-mode,
+ haskell-mode, tuareg-mode, ...
