I don’t know anything about web tech or authentication, but I see that github has an API to create issues, would it be possible to create an issue from the supercollider IDE? Perhap a button in the top of the help browser saying, ‘improve me’, that opens a copy of the help file, which the user edits and saves somewhere, then passes the filename as a supercollider string to some class which opens a page in the help browser asking the user to login to github, following which an issue is made.
This wouldn’t actually alter the users supercollider install, they wouldn’t be able to see their changes when they browse the docs, which should avoid a bunch of issues.
Having knowledge of git & github to fix a typo is a big hurdle, having an account is less so.
This would also communicate directly with all users of supercollider, rather than the small subsection who hang out here.
Similarly there could be a ‘submit a bug report’ or an ‘ask for help’ button, the latter could open this website.
