Select mutiple lines at once in diff view
As a user using the diff view (before staging changes or resolving conflicts), I would like to select multiple lines at once (using drag-and-drop, shift-click or whatever) in order to avoid clicking every single line in the right order, which can be a real pain when dealing with 200+ lines.
As I frequently split my work across multiple commits and since the hunk view doesn't help when two different pieces of code are contiguous, it would really be a killer feature to me !
