[Kimchi-users] Kimchi time-out

I find myself being auto-logged out of Kimchi often, and after seemingly short periods of inactivity. Also, it seems to depend on the Kimchi page or dialog I'm on, although I may just be imagining this. Can someone explain the Kimchi timeout policy, why it exists, and whether there's a way to change it or shut it off entirely? (And if not now, or yet, is there an outstanding request to allow the timeout policy to be configurable? Or is there some inherent reason it is what it is and will never be changed?) Thanks
