Right now, "hiding" a profile totally deletes it. This has some interesting effects on profiles that are in active use - their icons and background images disappear, and their closeOnExits get ignored. Anything that relies on the presence of a profile for a given tab fails.

I'm wondering if hidden shouldn't just mean "don't show in the list". This has other interesting follow-on questions: should a profile that's been hidden still be launchable with a keyboard shortcut that specifically targets it? should a hidden profile be defaultable? I don't totally see why not.

Partially related to [workitem for customizing the dropdown menu].
