Login expiration notification

Hi,

I really like that you can stay logged on in altrady for quite some time, which is very useful as I often keep it open in the background for notifications and alerts. What I'm missing though is that when this period expires you get quietly logged out, which also causes you not to receive any notifications the rest of that day. I'd really like it to receive a notification when this happens so I can login straightaway again.

Cheers!
