How to retore those buttons that show/hide the extra windows?

  • I recently bought a Surface Pro and installed Clip Studio EX on it. When I started using it, the default layout had these buttons docked to the side and when you clicked on them, they would show/hide the brush size, color palette, layers and all the other useful windows. This isn't the << button at the top of the dock area but something specific for the different windows.

    Anyway, Windows 10 then decided to update itself and caused Clip Studio to crash. When I restarted it, those buttons were gone and replaced with the more conventional layout that I have on my old desktop PC. Is there some way to get those buttons back? In the few hours I was using them, I found them very useful.
