Sorry, but it cannot be resized or maximized at this time. Perhaps in a future version. You can try messing with the Windows DPI scaling settings and the setting in the TM regarding the same.
Yeah, I tried messing with those settings, it made it MUCH worse, even bigger than the screen could see. The smaller I tried to make the screen, the worse and more giant it became. I will just have to wait for that option in resizing the manager. Thanks anyway.
