Great upgrade to the unpaywall extension!

Since I am/was a user of that extension, OAHelper's color scheme confused me: I associated a green badge with green Open Access, i.e. the OA version is available at a different location; and a gold badge with gold Open Access, i.e. it is available "here" at the publisher. OAHelper does it the other way around, which is based on a different philosophy (green = all is good, stay here; orange = oops, you don't get it here). But given that OA levels are associated with colors, did you consider to flip those two colors - or provide an option in the settings?

I have a feature request: the unpaywall extension treated the link in the badge as a regular link, so that on hover, one could see the target URL in the status bar. OAHelper does that different, so that one has to click the badge to know where it leads. Any plans to make it a regular link like the unpaywall extension did?

Thanks for your work! Highly appreciated.
