arrow down pressed on last visible row

[jtorjo]

it now slows the UI and it doesn't look cool (the selection basically is shown as going up, and then down again).

I should now show the selection while scrolling down.

perhaps for consistency, I should do the same for arrow up?
to look at pgdown/pgup as well

this is a very weird issue - seems to actually happen only when going full screen. also, it seems to happen only on the view that was active when i went full screen. now, that i made the selected row much less intrusive, this is not such a big issue, but it's still rather annoying
