So you want to be able to stream Gimp and have a shared drive with your PC’s sheets, it needs to be open source and with no limitations?
I’d just do gimp+Discord+google docs, but if you want it to be open source and all-in-one then go checkout Nextcloud. I think that’s as free as you get, if even foundry is too limiting.


Oh damn!.. I’ve never crossed Bookstack in my searches, but from the previews it looks (actually) simple, clean, and powerful.
Now I know what the evening will be spent on!
