I don’t know about you, but I am tired of having to remember the dozens of simple, one-off workarounds to every single thing I want to actually accomplish.

A few months back I had to sanitize the commit history of a repo that needed certain files removed from the entire history. I could have read the manpage for `git filter-branch`, but in jj editing commits is just a normal, sane part of your workflow. It was a blindingly obvious one-liner that just used all the commands I use every day already.

Even better, it was fast. Because “edit the contents of a bunch of commits” is a first-class operation in jj, there’s no need to repeatedly check out and re-commit. Everything can be done directly against the backing repository.
