I'm sorry for any confusion, but the extension seems to have worked as described. I took time to detail every action in the description, so I supposed you didn't read it. Additionally, warning messages appear for each icon when you hover your cursor over them. Receiving a 1-star rating for an open-source extension that I put effort into coding and that worked as intended is kind of disheartening, but hey, that's just the way things work online, I suppose. I will take your comment into account and consider adding a "careful" introductory popup later on. Cheers.
