So much this! The biggest and most massive of +1's possible My group wanted to play a Total Conversion homebrew of DnD 5e, being able to adjust and add to the compendium, as I see fit, to match what's in the homebrew, add traits, feats, rules, backgrounds with traits, classes, races and everything, just blow the gates open on it, would be amazing, I almost went with DiceRight because they offer this feature, but eventually got pressured into continuing to use Roll20, the real work is gonna be on the players and GM's adding to it, and that's okay... And if the feature is added, allow a GM to make a participant co-GM temporarily so they can add to the compendium as well, making it a group effort.
