Yeah that makes sense, (something I haven't encountered as much myself since I don't really use flight
). I'd say this probably doesn't even need to be an option, just add it as automatic behavior as we already have for the SLOW warning? I can't imagine someone really wanting to turn this off, since at most you'd only want to do this temporarily, and a warning when it once again becomes an issue would be a welcome reminder.
I'll add it for Beta 9.
