Recent reviews

Hello, can you support shortcut keys to switch back and forth between two split screens? For example, to switch between 7:3 (with the ability for users to customize this ratio) and 1. There is also a bug where, after selecting option 1 or closing a window, the window is not fullscreen; there are gaps around the window.
