User Interface Tool

[PicassoCT]

Hi, wouldn`t it be cool to have a tool, that calculates how much time the Users spends before, and after he hits a button, before he is able to do another click ? That way, we could easily find out, which buttons are most time consuming and need automatisation ideas. It would be also pretty helpfull, if this Tool would count how often one button has been hit, and which Combination of Buttons, reapears more often. Thx for reading.
