blazingly fast and very neat! since I'm the first user to use this add-on i have some constructive criticism to point out:

1/ the spacing between Sentiment: and number is a bit unnatural, you should reduce it

2/ you should add the % after the sentiment number, it's confusing at first glance tbh

3/ give us (me and soon-to-be-new users) an option to show x, y, z corresponding with negative, neutral and positive just like with what Return Youtube Dislike add-on does

4/ the text and rating bar should be in a gray pilled-style background like the other buttons for esthetic reasons

5/ has the option to just hide the text and show the color bar as a loading bar-esque UI for minimalism. When users hover/unhover their mouse over the background, the Sentiment rating should appear/disappear
