How would you compare this to, say, McFly? https://github.com/cantino/mcfly

Not too different.

* We use heuristic based searches whereas mcfly trains a neural network * We offer a sync functionality to share history on multiple machines

mcfly is a great project, although they are looking for new maintainers apparently!

Intrigued by local-directory-first feature of McFly (It brings up commands you previously executed in that folder first). I tried it for a bit. But there was noticeable lag compared to FZF and also the UI was a bit shaky.

Went back to FZF (in Zsh).

I have a seven year zsh history. That may be a contributing factor for the issues ?

Oh, it's nice you fixed it, thanks! And don't worry, I updated atuin, as it's in my distro's repository (which is why I wasn't worried about disabling the update check).

I noticed that before and am glad to see it fixed. My current issue is that typing to search is noticeably slow on a 150,000 entry history, especially for the first few characters. fzf is instant for me.
