Aha - I was using this completely different tampermonkey extension that also hides resteems - I wrongly assumed it was yours.
I've installed yours now and can see the require line.
When I required Jquery in my own code I got a browser error due to cross-domain access of the script file. Maybe I'll look at that again now I have your code. thanks!
Gotta love programming! Or should I say 'Problem Solving' lol
