Maplestory at custom resolutions

for my own use, I dont mind if maplestory's internal resolution is 1366x768 (despite me running higher). I just want the ability to scale some of the UI elements(similar to how the minimap has 3 modes) as well as stretch the window, but keep its windowed aspects. I hate how the game either gives you stock windowed mode, or fullscreen with a lack of fullscreen windowed mode.


tl;dr if the game had fullscreen windowed mode and the ability to make some elements in the UI smaller(e.g the soul weapon bar, smaller quest meter) then I dont mind having the 1366x768 resolution.
