Sorry Filip - I'm working from home and can't seem to log in to discuss (long story).

  IMHO - It would be nice to be able to clear the list, but as long as it clears on its own at the end of the session I wouldn't see this as a terribly high priority.   Depending on what information displays others might see it as more important.

Either way, a small button somewhere would do the trick.  It certainly doesn't need to be like the giant one on the check out screen.
