Maplestory at custom resolutions

A full screen windowed mode would be great with how often this game crashes. I hate how you can't do anything during the loading screen if the game closed while full screen.

They need to just make resolutions higher than the bargin-bin 1366x768 official options in game. I can't imagine them being terribly difficult to implement. If we had at least 1920x1080, I'd be fine with that for a while.

EDIT: And a stretch-to-fit-screen-size window mode would be good, too.
