Agree, I added the '.' command to simulate '!' (repeat last command) since you end up iterating commands quite a bit (until you reach end of network level, where it becomes trickier). Not sure if mouse clicks would help this, though...

No, mouse is bad idea. Please add command-line completion (tab key) and command history (up key) like in BASH. It's good way to make game better.
