KRunner should learn which selections you use the most (see Quicksilver on the Mac).

Use case: this is the first time ever I run KRunner. I type "fi", and "fillets" shows up first, then "firefox" second in the list of hits. I select "firefox". Now "fi" gets an increased score for "firefox", and "firefox" also gets an increased score. The next time I type "fi", the hit list will have "firefox" first and "fillets" second.

However, on typing "f", "firefox" will also be on top, since "firefox" itself got an increased score. This is because I've never selected any program before on the "f" prefix, so it has no prefix-score, and KRunner falls back to looking at the app scores themselves (which in the simplest implementation would just be the sum of their prefix scores).

"Special commands" like = might have to be exempt from this.

It already does this for me, although it requires at least 3 letters before it provides any information (which is necessary for performance).
