-- Make texts translatable
-- Do not use QErrorMessage, Creator standard error instead?
 Commands:
- - P2:
-        - branch [list, create, delete]
-        - checkout [with/without creation]
-        - combine both above to a single dialog?
  - P3:
-        - stash [creating, listing, applying]
         - allow to use external viewer instead of greenhouse one
           as these have more functionality usually
 
 GUI:
  - Better diff view
- - Commit view View (reuse diff view?)
  - Commit action View
         - Able to add further files to commit (list of modified/untracked files)
  - use List for Log (and allow 10+ entries)
-        - Have commits clickable for 'git show'
 Backend:
  - Don't use forked processes, instead find a library connection like libgit-thin
         - http://repo.or.cz/w/git/libgit-gsoc.git
