β22 is now available! You can finally push/pull branches from within Retcon—but not without a couple of twists.
First: pull whenever. Even with changes in your workdir; even in the middle of a conflict resolution. (maybe missing upstream commits are causing the conflict?)
Second, and much cooler: Easily, safely undo a branch push. Just hit ⌘Z, and that typo never happened. Nothing to it!
