From the Kickstarter announcement of the Roll20 Module: However, this package does NOT include a Compendium for integrating spells, subclasses and magic items into your Roll20 account interface. All subclasses, spells, and magic items are still included in the package (with all artwork included), but they appear as "handouts" rather than integrated features. What this means is that spells and class features will need to be copy/pasted into your character sheet rather than drag-and-dropped, as you might for other "official" content. The reason for this is that, as Roll20 moves to integrate with OneBookShelf, they will be moving away from the "Compendium" format, and so we were advised not to use that feature for the time being. Which (setting aside all concerns of the current functionality of this particular product), if that is all accurate, hints at some really interesting behind-the-scenes developments on the Roll20 platform that could shift the way character sheets and product content work.
