So, uh, how do I undo my colorways selection? On opening after the new update it gave me a little panel to choose from, and I picked one, but I don't like it now... but I can't see anything in the settings to revert, or to try a different one? I don't see anything about it in the "Colors" section of the Settings, and searching at the top for "colorways" doesn't return anything. edit: Found it! In the settings on the bottom left you can choose "Extension & Themes", and then you click "Themes" in the new sidebar, and scroll down a bit.
