It would be nice if the app finder would remember last apps and suggest them as first result while we are typing. 
It already remember last string entry but the suggestion could be enhanced in the above way, example:
- suppose I type "terminal" I select "xterm" with arrows from app list and then I execute "xterm".
- next time I type "ter.." app finder should show me as fist item " Xterm"

Also It would be nice if at this point just pressing "enter" I will start "xterm" (autofocus)
