Convert notes to Solfège representation on Freetar site. This extension was originally meant to be used on the original Ultimate Guitar, but HTML is way harder to edit there, also Freetar removes a lot of UG bloat.
This extension has been tested, but it may not cover all use cases, if you happen to use it and find an error, please let me now.
When viewing changes on-the-fly when developing, you can run npm run start and load the uncompressed extension
by pointing to the dist folder in chrome://extensions/
