Not a big deal, but I noticed that my Trinket Slots and Weapon Upgrades always notify me when they expire. However, my elevator pass doesn't do that, so I end up not realizing that my month's up until I go down an elevator and it actually uses energy for a change XD I can't remember if I've been notified on Heat Amp expiration, but if not, that should be implemented as well. But yeah, it would be pretty helpful if I got a notification when the elevator pass expired in the same way that the Trinket/Weapon Upgrades do :D

I can't see how this notification would *bother* anyone (correct me if I'm wrong), and it would certainly help the people who could use it.
