Fullscreen Minimize and Maximize on Application

Idk if you guys are working on this, or if we have to implement this manually into a game window/application but, is it too hard to create the same minimize/maximize window options in the upper right hand corner of the game window when it is in fullscreen. It sucks that you can't switch back and forth between fullscreen and windowed unless you program it into the game itself. More importantly, does anyone have a solution for creating a window application that can minimize and maximize itself?

My issue is that, I can get it to be windowed however, once I maximize the program into fullscreen mode, it stays there and the minimize/maximize window options that are in most programs aren't there. Idk if this is something done on purpose but, is it possible we can have this option since the Resolution Dialog is going to be deprecated in later versions of Unity.
