Not Sure if this makes sense but it would be extremely nice to have some sort of tool that handles the entirety of uploaded content for a game. Art Library, Assets, Jukebox, Compendium, Journal, etc. The new Asset Library UI updates are an improvement from the previous iteration but having some sort of external tool that could handle folders, playlists, and any sort of way Roll20 supports Organizing content and being able to reformat for your game would be extrememly helpful and probably save a lot of GMs time. TLDR; an external file explorer for a game that can reorganize content with less clicks.
