I agree that it sometimes needs to be turned off but indeed it’s on rare occasions. Still using it and still loving it. I ended up really liking the “focus follows mouse” feature, too — even though I would consider it work in progress as floating windows or the menu bar are more like a pain in these situations with that specific setting. I’ve commented on the devs Github, so we’ll see.
In the meantime I would be really happy to find some “write defaults magic” which I can tie to a shortcut to enable/disable “focus follows mouse” on the fly without interrupting my flow. The only thing I’ve found so far seems to only work on the terminal, so for now I guess I’ll have to live with it (which I can, but of course I’ll keep digging).
