Glad to hear you found the online resources (you mean the Play Aids folder?). Making good online character keepers is a fine art and I’m really happy whenever I discover somebody bringing new optics, new spreadsheet wizardry or whatever into their keepers.
I personally am totally fine with rolling real life. It goes much faster and especially in systems where you roll frequently, it’s what I prefer.
Then again, the feel to stare together at the RFYP room and see how your plans collapse collectively as its very own appeal.
As I play mainly online, I can’t really say what works specifically well.
What I can say is that those games which specifically make use of online technology are super cool. The LAOGs (live-action online game) I designed are made for this purpose. But TTRPG can benefit from being together online, too. I like to have image boards (Google Drawing) where one can quickly drag and drop an NPC portrait or an image for the scenery. You can also play with the immersive fact that muting yourself can have an in-game reason. The frustration of only being able to text message becomes very real quickly.
