True, the prompt is easy enough to understand. There are two main issues with it:
1) Every 60 seconds the prompt times out. If a user is entering his credentials at this point, he will hove to start over.
2) If you accidentally enter the wrong username, you can't go back and change the username. Instead, you just enter the wrong password and hit enter.
Anyway, if no one want to create an extension I'm sure I can live without it. Perhaps someday I'll have learned enough to do it myself.
Also since no one else is running a display manager it is probably better that no one submits one since, generally speaking, it is best when a developer actually
uses the software that he is maintaining.
