Show which keys are being pressed (on midi controller) in the piano roll

It would be cool if when you hold down a key on whatever midi controller you're using then the corresponding key on the piano roll gets highlighted. I guess really i should know what keys i'm pressing, but i'm using a microkorg and it gets a bit confusing no having all the keys there... It would be really handy when you want to draw in something that you have been jamming out on the keyboard. Apologies if this is already an option, i tried searching but the words were too general to come up with anything relevant.

This is already in the FR tracker, I think: and So vote there!
