Timeout as in disconnect them? Not an option as it stands now within Plex Media Server.
There are already several requests like this on this particular sub-forum. I suggest rather than starting a new one, find one that already exists and add you "Like" to the first post. This is how the voting happens in this forum. We don't want to have too many feature request for the same types of things, and have the votes all scattered around.
If you have an idea for something different, elaborate on it, since this is somewhat confusing to understand what you want to do...
