Hey, so I was trying to set up a page for an RPG supplement earlier this week and one thing that stood out is that there's no (obvious?) way for me to do revenue sharing.
Aside from my tabletop development work I also write technical stuff and publish through Leanpub - one of the best features available there is the ability to add contributors to my books/projects and share revenue directly with those folks. Below is an example of the sort of UI I mean.
For a lot of us collaborating on projects it'd be super helpful to be able to do a transparent revenue split at the project level - this way we could say allocate 40% to the artist, 20% to the person who did layout, etc.
Another feature LeanPub has which I would love to see Itch adopt is the ability to earmark a percentage of royalties for non-profits. I am a contributing author/editor to a book series the royalties of which go straight to the non-profit instead of the authors - I would love to have a way to do this here for TTRPG projects.
Otherwise, pretty much echo everything else said in this thread and thanks for making an incredible platform!
