Thank you so much for this, works perfectly.

Works like a charm.

I wasn't expecting this to work but it does! I'm impressed by your work Xmader, you are truly a hero to me.

Allows me to get my musical sheets free of charge which is excellent, I can teach myself and reduce the costs of it, or take music sheets printed out to my friends place to perform which is just great. It would be nice if the extension would feature a guide on how this extension works because it isn't really clear, but you'll understand it as soon as you get into the music sheet website so it's not too big of a deal!

It worked really well until recently, where it seems there was a new update to librescore and it doesn't work anymore

Excellent addon against awful monetization scheme where you should buy sub to download sheets made by users.

Amazing. Thank you very much.

Awesome. You're doing a greaat service. Works exactly as it is supposed to
