One feature that “Sourcetree” (software I was using before Sublime Merge) had that I miss is to quickly revert hunks from the UI when looking at a commit or ranges of commit.
It would be similar to discarding a whole file or a hunk in the working directory mode (or staging):
It is one of the few features that I think are missing from Sublime Merge, or it’s there and I don’t know how to do it yet.
