I have never considered something like that, I didn't even know that was a thing!
Currently, I don't think it is feasible for me right now, for a few reasons:
1) I still tinker with it, even just minor things. The current version is very good and as "complete" as I have ever gotten it, however I still like to tinker, take community feedback, and make improvements as I use it for playtesting. I don't know if I like the idea of a "static" product.
2) I don't really have the time nor skills to do this properly. I would need professional layout software, I would need to manage proofing, ordering, shipping, etc. All of which would be doable, except...
3) I don't intend to monetize this product. I want it to remain free to all, with a low barrier to entry, so anyone can enjoy their games. Currently, printing a single page of paper is about as cheap and easy as it gets.
Now, with all that said, I do plan on getting all my sources, tables, images, etc released on Github so that anyone can recreate the pocketfold, or integrate it into their VTT/App of choice. If someone wanted to order themselves a higher quality version, nothing would be stopping them. But I do believe the licensing means no one else can sell it.
Thanks for the idea! I may revisit this in the future.
