Very cool that GitHub actually put stacks in the UI vs. GitLab's `glab stack`[0] (which looks just like the `gh stack` part of GitHub's thing).

One part that seems like it's going to feel a little weird is how merging is set up[1].

That is, if I merge the bottom of the stack, it'll rebase the others in the stack, which will probably trigger a CI test run. So, if I have three patches in the stack, and I want to merge the bottom two, I'd merge one, wait for tests to run on the other, merge the second vs. merge just those two in one step (though, without having used it, can't be sure about how this'd work in practice—maybe there's some way to work around this with restacking?)
