In the various forum spaces, there seems to be alot of missing functionality within the various compendiums (namely Tasha's cauldron of Everything for now), I feel it would be better served to add a try it before you buy it option on things like the Dev server. I understand why you might not want to implement this on a basic level, or even on a "Plus" level. However a great marketing technique would be to allow Pro subscribers to try a particular rulebook out on the dev server, so they know that the book works to their expectation. You can even include a time-out function that requires a user to test the functionality for X days/hours/etc, and if they want it after that, or for production, they'll need to pay for it. This is mainly a suggestion to prevent more bad-mouthing regarding paid content on the site that i've see a bit of lately. You wouldn't need to add in the artwork, as that could be mis-used by unscrupulous users. However including things like the charactermancer items/classes/races/etc, should be relatively trivial.
