This would be SUPER helpful when you've downloaded an entire romset for a certain console (or certain version of mame). Simply ANYTHING that would move ROMs you've chosen to the top of the list (instead of having to scroll through like 3,000+ ROMs, or hit select, then select a letter, then still have to hit L or R bumper to page up/down through like 100+ ROMs to find the ONE SINGLE GAME you want to play!)

@Rookervik: That is completely understandable and you have my apologies. I look forward to seeing it in its completed state when you are ready to release it to the world.
