I was around for the old Customs site and you have done amazing work, making these so much more accessible to everyone. Thank you.
I'm sorry for your loss, I'll certainly help with the Patreon.
Just came across this https://github.com/Jamedjo/RSTabExplorer/releases It takes RS custom and exports it to a tab sheet (kinda like GuitarPro). This is great for me since I like to look over the songs tab and get an idea of how a song goes before I jump into RS and play it.
