I super appreciate the gesture.
Do you need it to be PWYW for the dropping a few bucks part or the add to the library part? Or both?
Huh... what a wacky spec. I presume this is with the itch.io Launcher, yes? I haven't actually used it in years. I'll check it out to see if there's an easy fix I can do on my end.
If you're comfortable sharing more info about your use case, would you mind contacting me by email at rob-at-skyboygamesDOTcom? I'd like to make sure I have details straight in case I need to log a bug with itch.io.
