My thoughts on this extension:

- remove the link to the class syllabus that you wrote this as a project for, pretend you maintain it at least please. Or a link to a GitHub page where people can see your source code and do the work for you if you are unwilling to do it, which also looks less... rough. PS anyone can pull your code from the extension bundle anyway, you are hiding nothing from people who are not using windows if that was your hesitation.

- there is no reason I shouldn't be able to select the color myself instead of three options you defined and used ambiguous labels for. Accept user input and add it to the CSS this then overrides the default with. It is hardly much additional code. The fact the icon color is not an option bothers me and makes it seem like that got more work than the underlying function (people want the reverse btw)

- single keypress doesn't work, key combo would be better anyway and some ChatGPT generated documentation with it

Doesn't work

Can't get it to work. A page pops up after clicking the icon. No matter what I do, going back to the tab where I need to highlight words, nothing works. This sucks.
