Constant oauth timeouts & overall bad auth behavior

It is totally annoying to constantly refresh oauth sessions. There should be a "trust this browser and stay logged-in" checkbox in the login form. Even better would be some kind of "device trust" and the possibility to manage the trusted devices. This way it'd be enough to login _once_ to have the desktop client working - instead of every day or another. The ever timed out sessions are even more annoying on the android client (same with beta).
