CodeMirror 4.0 is about to be released. We should give it a try by testing and maybe updating to the release candidate.

The major new features in 4.0 are: 
 - Multiple selections (ctrl-click, alt-drag, and API functions to 
work with them) 
 - Selection undo/redo (ctrl-u to undo selection and alt-u to redo 
selection in the default keymap) 
 - A set of Sublime Text keybindings (see [4]) 
 - All modules are wrapped in AMD and CommonJS module loader shims, so 
that they play well with module loaders. When neither is present, the 
old style (global CodeMirror variable) is used. 
 - A new character measuring subsystem that is faster (especially on 
long lines) and more robust (no more problematic corner cases in 
wrapped text). 

The last point is the most interesting to me and should fix some long standing issues.
