Bind set-case-syntax-charset to iso-8859-9. Never provide latin-5.

                                                                -*-text-*-

* Bring back the feature of showing the part of the buffer that is a problem
  for the use of the preferred coding systems.

* Provide user-friendly ways to list all available font families,
  display a font as a sample, etc.

* 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.

* Program Enriched mode to read and save in RTF.  [Is there actually a
  decent single definition of RTF?]

* 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.

* Implement something better than the current Refill mode.  This
  probably needs some primitive support.

* Implement a clean way to use different major modes for
  different parts of a buffer.

* Give start-process the ability to direct standard-error
  output to a different filter.

* Make compile.el record the markers that point to error loci
  on text properties in the error message lines.

* Make desktop.el save the "frame configuration" of Emacs (in some
  useful sense).

* Make movemail work with IMAP.

* Add ANSI C prototype forward declarations to the source files,
  so that even the functions used within one file have prototypes.

* Replace finder.el with something that generates an Info file
  which gives the same information through a menu structure.  [Dave
  Love started on this.]

* Implement a variant of uncompress.el or jka-compr.el that works with
  GNU Privacy Guard for encryption.  [Code exists but isn't assigned.]

* Save undo information in files, and reload it when needed
  for undoing.

* Change the Windows NT menu code
  so that it handles the deep_p argument and avoids
  regenerating the whole menu bar menu tree except
  when the user tries to use the menubar.

  This requires the RIT to forward the WM_INITMENU message to
  the main thread, and not return from that message until the main
  thread has processed the menu_bar_activate_event and regenerated
  the whole menu bar.  In the mean time, it should process other messages.

* Implement the design for Unicode-based internal encoding for Mule.

* Get some major packages installed: W3/url (development version needs
  significant work), PSGML, Mule-UCS, Tramp (?).  Check the
  assignments file for other packages which might go in and have been
  missed.

* Make keymaps a first-class Lisp object (this means a rewrite of
  keymap.c).  What should it do apart from being opaque ?
  multiple inheritance ?  faster where-is ?  no more fix_submap_inheritance ?
  what else ?

* Provide real menus on ttys.  The MS-DOS implementation can serve as
  an example how to do part of this.

* Implement popular parts of the rest of the CL functions as compiler
  macros in cl-macs.

* Highlight rectangles (`mouse-track-rectangle-p' in XEmacs).

* Support simultaneous tty and X frames.

* Implement primitive and higher-level functions to allow filling
  properly with variable-pitch faces.

* Provide MIME support for Rmail using the Gnus MIME library.

* 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.

* Fix anything necessary to use `long long' EMACS_INTs with GCC.

* Split out parts of lisp.h and generate Makefile dependencies
  automatically.

* Update the FAQ.

* Allow auto-compression-mode to use zlib calls if zlib is available.
  [It's required for PNG, so may be linked anyhow.]

* Add a --pristine startup flag which does -q --no-site-file plus
  ignoring X resources (Doze equivalents?) and most of the
  environment.  What should not be ignored needs consideration.

* Investigate using the language environment (or locale?) to set up
  more things, such as the default Ispell dictionary, calendar
  holidays...

* Improve the GC (generational, incremental).  (We may be able to use
  the Boehm collector.)

* Port Emacs to GTK+.  (Relevant work has been done already.)

* Make the Lucid menu widget display multilingual text.

* Check what hooks would help Emacspeak -- see the defadvising in W3.

* Implement some variety of (non-gtk) drag-and-drop support under X.
  Using libdnd might be a good start.

* Remove the limitation that window and frame widths and heights can
  be only full columns/lines.

* Add horizontal scroll bars.

* Provide an optional feature which computes a scroll bar slider's
  size and its position from lines instead of characters.

* Implement a smoother vertical scroll facility.

* Integrate Vroonhof's Custom themes code and make it do useful
  things.  [The integration is partly done.]

* Adapt the gnuserv/gnudoit features for server/emacsclient.

* Investigate using GNU Lightning or similar system for incremental
  compilation of selected bytecode functions to subrs.  Converting CCL
  programs to native code is probably the first thing to try, though.

* Add a feature to Info similar to "info --apropos SUBJECT".

* If you do an insert-file and that file is currently modified in
  another buffer but not written yet, print a warning.

* Add support for SVG (Scalable Vector Graphics) rendering to 
  Emacs.

* Use the XIE X extension, if available, for image display.

* Rewrite make-docfile to something sane.

* Port the conservative stack marking code of Emacs' garbage collector
  to more systems, so that we can completely get rid of GCPROs.

* Maybe document the features of libraries missing from the manual (or
  ancillary manuals, including the Lisp manual in some cases).
  This is not worth doing for all of these packages and we need not
  aim for completeness, but some may be worth documenting.
