The grid, which is entire reason for using the Roll20 product, aligns to the left side of the screen. At present, this means parts of your map will be obscured by chat avatars and other UI elements at any zoom level in which your tokens are actually discernible. It also just makes the process of editing maps and scrolling through them or zooming in or out frustrating and awkward. Centering the work area within the UI will also bring it in line with nearly all other modern software in existence, making it more comfortable for all users.
