I've rated 5 stars because the extension does work as intended, providing everything you said it would which is great! But I did install due to a misunderstanding which was my fault though maybe you could implent some of the features opera has if possible (e.g the alt + left clicking to close tabs, the image selection ui that shows the last image you copied and those that you recently downloaded when posting an image somewhere)
if not that's completely understandable, but thought I'd suggest it at least. Thanks for making the extension :3
