Please please please bring back the ability to resize the window to arbitrary dimensions! Now I can only pick from the preset dimensions via the option menus. I'm a Linux player and I had hotkeys for resizing the window, but now that it doesn't let the user resize it (other than the options menu) my hot keys don't work. It was bad enough when the game started restacking itself and I could no longer have other windows overlapping my game window without setting them to be always on top or forcing the game to stay on bottom, but since I could resize it, I could stack other windows around the game window. Now there's a ton of wasted space if I pick a preset size that's too small, and not enough space if I pick a preset that's too large. Anyway, love the game, hate this new default, I know it's a small thing, but I'd really like to get this feature back and it seems like this is just a checkbox setting in Unity, so it should be easy enough to re-enable.
