+BUGS:
+
+- when there's a selection, typing ^X will delete the selection!
+ (cause: ^X is a binding for cut ;-( )
+
+TO DO:
+
+- restructure state sensitive code to avoid testing flags all the time
+- integrated debugger
+- object browser
+- save some user state (e.g. window and cursor positions, bindings)
+
+- menu bar
+- make backups when saving
+- check file mtimes at various points
+- interface with RCS/CVS/Perforce ???
+- more search options: case [in]sensitive, fwd/back, string/regex
+- global query replace
+- incremental search
+- more emacsisms:
+ - reindent, reformat text etc.
+ - M-[, M-] to move by paragraphs
+ - smart stuff with whitespace around Return
+- status bar?
+- better help?
+
+Details:
+
+- when there's a selection, left/right arrow should go to either
+ end of the selection
+
+Structural problems:
+
+- too much knowledge in FileList about EditorWindow (for example)
+
+======================================================================
+
+Comparison to PTUI
+------------------
+
+- PTUI's shell is worse:
+ no coloring;
+ no editing of multi-line commands;
+ ^P seems to permanently remove some text from the buffer
+
+- PTUI's undo is worse:
+ no redo;
+ one char at a time
+
+- PTUI's framework is better:
+ status line
+ menu bar
+ buffer menu
+ (not sure if I like the toolbar)
+
+- PTUI's GUI is a tad ugly:
+ I don't like the multiple buffers in one window model
+
+- PTUI's help is better (HTML!)
+
+- PTUI's search/replace is better (more features)
+
+- PTUI's auto indent is better
+ (understands that "if a: # blah, blah" opens a block)
+
+- PTUI's key bindings are a bit weird (DEL to dedent a line!?!?!?)
+
+- PTUI's fontify is faster but synchronous (and still too slow);
+ also doesn't do as good a job if editing affects lines far below
+
+- PTUI has more bells and whistles:
+ open multiple
+ append
+ zap tabs
+ fontify (you could argue it's not needed in my code)
+ comment/uncomment
+ modularize
+ examine
+ go

+
+ ^S without a selection opens search dialog box
+ ^S with a selection searches for selected text
+ ^U ^S repeats last search
+ Alt-G opens dialog box to go to a specific line

+ Backspace deletes left of cursor, Delete right of cursor
+ Cut and paste use platform's conventions
+ ^[ or Alt-[ left-shifts (dedents) the current line or selection
+ ^] or Alt-] right-shifts (indents) the current line or selection
+ Alt-/ expands last word you type (like Emacs dabbrev)
