I would like to be able to share my compendium, with the 5e Monster Manual and Volo's and any future compendium expansions, with my players. This functionality is available through D&D Beyond as part of their Master subscription tier and through Fantasy Grounds as part of any of their subscription/license tiers. I would like something similar for Roll20. As part of either Plus or Pro subscription (Pro makes more sense to me), give the ability to share content either with a specific number of players, with a specific number of games, or with all games the subscriber creates. This would give extra incentive for people to subscribe, and it would provide functionality that is available on Roll20's competitor sites.
