I found <a href="https://app.roll20.net/forum/post/4788870/creating-my-own-compendium" rel="nofollow">https://app.roll20.net/forum/post/4788870/creating-my-own-compendium</a> from a year ago, which offers some suggestions, but making a library campaign with source material handouts won't enable any of the compendium integration features (drag & drop, compendium buttons, etc). Have there been any updates in the past year that would allow for homebrew compendiums?
