Pianobook libraries (the page for a library) should include a Release Version Number to have a way to identify if a release has been updated for whatever reason, if bugs or quirks have been corrected and the library has been updated. You could update the release version if you upload an updated version of your library.
Also a way to get notified of new releases (updates) to a library you’ve downloaded would be a very nice addition.
I’ve run into libraries that had looping problems on one of the sampler flavours and I noted that in my review of one of them for example. Now if the author corrects the loop-points and re-uploads the library, I have no way of knowing this, but I’d love to, because otherwise that library would be a flawless and beautiful tool….
Just my 2 cents here 😀
