Could it be possible if the shortcuts would notify users when a new one was added, by highlighting the button with a different colour for example?
EDIT1: I know I am not going to be checking that shortcuts button all the time, so having the website tell me when something new has been added would be a nice improvement.
EDIT2: ARGHHH post edit history!!! NoooooOOOOoo!
EDIT3: FYI the edit history time stamps are incorrect
