-* Small but important fixes needed in existing features:
+* Simple tasks. These don't require much emacs knowledge, they are
+suitable for anyone from beginners to experts.

 
 

-** Make "emacs --daemon" start emacs without showing any frame. 
-Use emacsclient later to open frames.
+** Convert modes that use view-mode to be derived from special-mode instead.

 
 

-** Make it possible to reliably turn on minor modes using "mode:" in the local 
-variables section.
+** Replace some uses of the preprocessor code in Makefile.in with the equivalent autoconf.

 
 

-** "Options -> Save Options" should save the font set via "Set Font/Fontset"
-I.e. mouse-set-font should use customize-face.
+** Major modes should have a menu entry.  Examples of modes that do
+not have one at the moment and probably should: text-mode, inferior-lisp-mode.

 
 

-** Compute the list of active keymaps *after* reading the first event.
+** Check if all items on the mode-line have a suitable tooltip for all modes.
+
+** edebug and debugger-mode should have a toolbar.
+It can use the same icons as gud.
+
+** Check what minor modes don't use define-minor-mode and convert them
+to use it.
+
+** Convert all defvars with leading `*' in the doc-strings into defcustoms
+of appropriate :type and :group.
+
+** Remove any leading `*'s from defcustom doc-strings.
+
+** Remove unnecessary autoload cookies from defcustoms.
+This needs a bit of care, since often people have become used to
+expecting such variables to always be defined, eg when they modify
+things in their .emacs.
+
+** See if other files can use generated-autoload-file (see eg ps-print).
+
+* Small but important fixes needed in existing features:
+
+** Flymake's customization mechanism needs to be both simpler (fewer
+levels of indirection) and better documented, so it is easier to
+understand.  I find it quite hard to figure out what compilation
+command it will use.

 
 

-** mouse-autoselect-window should wait to select the window until
-the mouse is put to rest or after a delay or both, so that moving over
-a window doesn't select it.
+I suggest totally rewriting that part of Flymake, using the simplest
+mechanism that sufficies for the specific needs.  That will be easy
+for users to customize.

 
 

-** In C-x d, the default if you type RET should be the directory name,
-but if you type M-n you should get the visited file name of the
-current buffer.
+** Compute the list of active keymaps *after* reading the first event.

 
 ** Distribute a bar cursor of width > 1 evenly between the two glyphs
    on each side of the bar (what to do at the edges?).
 
 
 ** Distribute a bar cursor of width > 1 evenly between the two glyphs

-** Make vc-checkin avoid reverting the buffer if has not changed after

 ** buffer-offer-save should be a permanent local.

 * Important features:
 
 * Important features:
 

+** Having tabs above a window to switch buffers in it.
+
+** "Perspectives" are named persistent window configurations.  We have
+had the window configuration mechanism in GNU Emacs since the
+beginning but we have never developed a good user interface to take
+advantage of them.  Eclipse's user interface seems to be good.
+
+Perspectives work well even if you do the equivalent of C-x 4 C-f
+because of the distinction between view windows vs file windows.  In
+Emacs this is more or less the "dedicated window" feature, but we have
+never really made it work for this.
+
+Perspectives also need to interact with the tabs.
+
+** Imenu could be extended into a file-structure browsing mechanism
+using code like that of customize-groups.
+
+** Display something in the margin on lines that have compilation
+errors.
+
+** Compilation error navigation bar, parallel to the scroll bar,
+indicating where in the buffer there are compilation errors.
+Perhaps we could arrange to display these error indications on top
+of the scroll bar itself.  That depends on to what extent toolkit
+scroll bars are extensible.

    list fonts, display a font as a sample, etc.  [fx is looking at
