I do have ux feature request:
I’d like to just right click on the selected lines and stage/unstage them.
Same for files: Instead of selecting each file, I’d like to extend my selection (i.e. while holding shift) and when right clicking on the selection, an option like ‘stage selected files’ would be awesome to have.
I am coming from Git-Cola and I really love this functionality. I switched to Sublime Merge because Git-Cola is to slow.
