The problem is that the Interface isn't using it well, and chops half of the menus towards the right side of the screen.
I think an image will explain it better:

And to the left, there is plenty of space! I tried to drag the panels to the empty left side but to no avail

Any ideas of how to solve this?
Edit: And lol, sorry for the size of the screen. I thought the boards had an auto-resize to prevent this.
