Auto login and IM un-grouping

Hey, my name is Mike and we have been using Spark around there office here quite a bit and like it very much. Just a couple of things I noticed that I have questions about.

When a user logs out from being signed in, the “Auto-login” button is not automatically checked after the logout. Not everybody at the company here is smart enough to realize that the “Auto-login” checkbox is not checked. So sometimes users are just logged off. Is there some way to make that never get unchecked?

Is there a way to ungroup IMs so they are separate windows?
