 PLANNED FOR VERSION 7.0:
 
--   REFACTORING:
-    Improve the interface between the generic GUI code and the system-specific
-    code.  Generic code handles text window with scrollbars, system-specific
-    code menu, toolbar, etc.
--   Support using "**" in filename for ":next", ":vimgrep", etc., so that a
-    directory tree can be searched.
 -   Store messages to allow SCROLLING BACK for all commands.  And other "less"
     like commands.
 -   "INTELLISENSE".  First cleanup the Insert-mode completion.
