Brainstorming

Stuff that could be improved in mac vim:

• add proxies to the title bar, call SetWindowChanged (see here for details) - gui_mch_update, gui_mch_flush. Window proxies see here: AliasHandle, SetWindowProxyAlias, IsWindowPathSelectClick, WindowPathSelect (and SetWindowModified of course)
• improved atsui stuff (draw_string_QD/draw_string_ATSUI)
  
• (more than one window per session...)
• generate "Press Enter or enter command..." message, tab, cmd-tab: more messages are generated
• trackpad scrolling is currently a bit jittery because left/right movement scrolls as well (so left/down movement jitters) done
• ctrl-click for context menu, then click somewhere else - another popup is opened done (not by me)
• (not mac specific) when a file is selected in :e . , the :pwd part should be stripped if the file is somewhere below pwd
• pum shouldn't flicker (don't redraw too soon?)
• use carbon events
• use hiview
• Vim->About should work
• use mac os built-in spell checker :-P
• activating left scrollbar doesn't really work
• repainting whoes (scrollbar on/off; select new tab via drawer, :set cursorline etc)
• :set cursorline should move highlight and cursor at the same time, currently cursor is moved, screen is redrawn, and then the line is moved (and the screen is again redrawn)
• Fullscreen mode ;-)
• :map <d-a-c> doesn't work (<d-s-c&gk; does work, though)
• scrollbar thumb should be of the appropriate size
• font selection dialog should be modeless
• font antialiasing that works! (aquamacs is able to do it)
• resize frame should only show allowed increments (better yet: life resizing)
• start to resize the window, hit escape, move mouse -- vim explodes
• drag-n-drop from/to tab drawer (cf. proxy icons as well)
• drag-n-drop tab reordering
• antialias doesn't work with macatsui, umlauts don't work without macatsui
• convert the ugly dialog boxes to sheets, add better keyboard support to them (if they are left as dialog boxes, they should be moveable at least)
• remove "Help" item from context menu
• Use FSRefs instead of paths everywhere
  

other mac text editors one can look at for some inspiration ;-):

• TextWrangler
• Emacs (Aquamacs looks the most polished) ;-)
• Smultron
• TextMate
• XCode :-P
