JJ-FZF
JJ-FZF is a text UI for jj based on fzf, implemented as a bash shell script. The main view centers around jj log, providing previews for the diff or obslog of every revision. Several key bindings are available to quickly perform actions such as squashing, swapping, rebasing, splitting, branching, committing, or abandoning revisions. A separate view for the operations log enables fast previews of old commit histories or diffs between operations, making it easy to undo any jj operation. The available hotkeys are always displayed onscreen for simple discoverability.
