This is great, the only issue I have with it is how domain exceptions are handled when the extension is enabled for all websites: there are no wildcards. This is annoying on sites that have many subdomains, for example all *.arduino.cc sites are buggy with the extension, so it would be a massive time saver to be able to blacklist all of them with a single entry rather than adding each one manually, and would also avoid missing any in the process.

Good functionality options when it comes to the actual typography settings it applies, but currently breaks a huge amount of sites. This would benefit *massively* from two things: 1) the ability to provide class names it will apply to, rather than entire domains. 2) the ability to use a picker to select elements it would apply to, or right click and use the context menu to apply to that element (and that choice being saved).
