The tooltips were atrocious, it said: “hide or show the composer panel”, which is 100% incorrect for when it is collapsed.

So I fixed the bad tooltip, and also added the nag cause it was a trivial change. If people complain about the new nag I guess we can revert to a non naggy X.
Next up, fix the atrocious tooltip when I hover over blue 1 or green 1
