Hello there, Alonicus! Thank you for this lovely reply!
Roll20 is stressful for me. You have to do lots of stuff, like put maps on different scenes, you have to configure all layers for maps, tokens are not system-specific and I don't like to use that three circle things, because I don't know which one should be HP, or AC. I don't know how to automate attacks and damages, probably I have to calculate everything by hand. Lots of work for a little bit of game session. Fantasy Grounds automates attacks, critical successes, conditions, and lots of other stuff. FG also has D&D2e and D&D 3.xe compatibility for custom games, but I guess there's no any pre-built-in official books.
Lots of details on game mechanics is a flaw, when you don't have an inner circle. Because you have to teach people everything all over again. And people don't read. It's exhausting. But I learned lots of inspirational stuff from previous editions of D&D. Examplars of Evil taught me how to create rival-but-not-villain NPCs, while Book of Vile Darkness and Book of Exalted Deeds taught me how could I use good and evil as a game content. 2E rules taught me the roleplay values of a character class. Also 2e had beautiful setting variety. I really appreciate that (mostly Dark Sun and Planescape ofc)
I don't know if you need it anymore, but I've found this: https://paragondashboard.com/ It's an online GM Screen tool which you can share (or save), it may be helpful.
