I just wanted to change my top bar color to purple and it's so complicated to do. I have to recreate the whole default theme from scratch and then tweak the purple. When I got to a result I liked I saved the preset. After a while I wanted to change the shade a little bit. I did so but I was not satisfied, and by mistake I clicked reset all, instead of Back. At that point I was screwed, had no idea where to find the saved themes, would have had to recreate the original theme once again so I gave up, uninstalled the extension and came here to write this review. Work on your UX because this is really awful.
