Hello, I just discovered that the “Theme options” tab changes when you drag it from the side of the screen to the bottom of the screen.
All the options dissapear (Layout and design, Typography, Buttons etc.) when you place this tab on the bottom of the screen. I tried holding the “shift” button down in combination with mouse scrolling but that didn’t work because all the tabs just simply seem to be gone.
I made a video which shows what i mean.
