First, try and build your maps outside of Roll20 and save them as images for uploading. Unfortunately, I don't know of a way to 'save' maps created in Roll20 except to take a screenshot. Next, understand that the Art Library is just a list of what you've uploaded or what freebies are available to use within your campaign; it's not what's actually contained within your campaign (those are your handouts). One way to organize the art library or handouts is is to use tags (I hate tags). I prefer to create subfolders and organize my content so my screen isn't so cluttered. If you want to organize it, you just need to get in there and do it. No need to remove it or start over; your assets are already uploaded. Just take the time to organize it as you need. When I setup my campaigns, homebrew or otherwise, I only use a few active pages/maps at a time so that, again, there's less clutter on my screen: Map Pages Landing Page (Players are dragged here after the current session so that they can't explore other maps) Workspace (for when I'm creating monster entries and linking tokens to handouts) Generic Combat Page (which includes an image of the linked pdf as the map layer) Overland Map with a Party Token (token usable by all players) Terrain specific Battle-Map which contains different variations of the particular terrain so that I'm not using the same 'forest' or 'arctic' battle maps Current Town Map with Numbered Locations legend (I also create a handout with the same image and legend) Any building interiors or dungeons I may need for the current story Any other pages that I might have I archive them so that it doesn't clutter my screen space when I need to use a different map page. Having a minimal amount of map pages makes moving the player ribbon to a different page much easier for me. Handouts are organized into folders: GM Only (Notes, Links to Setting/Region/Settlement/NPC handouts, random tables) PC Only (PC Sheets, PC Journals, Quest Log, Loot) Setting Information with Regional and Settlement subfolders. I enable handouts for player viewing as needed. NPCs organized into subfolders; Monsters (by Type). Humanoids and Named NPCs have their own section with appropriate sub folders (General, Bugbears, Goblins, Orcs, etc.). I put descriptions into the Bio/Info tab and then use the Show To Players handout button to give them access to the Bio/Info tab of handouts. Magic Items; add/copy them as handouts and when a player claims them, assign the handout to those players so they can look up info for themselves. Game System Information; Armor/Weapons/Equipment charts, Conditions quick list. I find that the Compendiums, although useful, still lacks with how I need to information. I've re-created the above charts in a word processor and then copy/pasted into a handout, giving my players viewing access. For purchased adventures (I only have one), I use the transmogrifier to bring in my own creations from other campaigns as needed. I don't want to manipulate the purchased adventure resources too much. I don't want to accidentally delete or alter something. Other Tips: Enable "Use advanced keyboard shortcuts" and then learn them to speed up your interaction within Roll20. Double check to be sure any custom macros work before running a session; Roll20 just recently updated the 5e OGL character sheet which broke a lot of my custom macros I found on the forums. Don't forget to toggle /talktomyself when testing macros or monster sheets to avoid accidentally sending the results to chat where players may read, possibly spoiling the surprise. Try to not use very large maps, or map pages with a lot of assets or drawings. This can reduce your bandwidth. If you are not going to be using any of the built in voice/video options in Roll20, disable it within your campaign to help your bandwidth.
