There must be a better way to quickly sort maps.

So I have a few map packs I like to use in my games and some are add ons that will load into the game already in folders. However these folders will have them in a random order that is not very helpful to find them when I need them. So I spend hour carefully rearranging these folders by clicking and dragging the maps until I get them alphabetized which takes forever and like 30% of the time the map just moves to the bottom of the list rather than where I want it. Please tell me there is an obvious easy way to quickly sort map folders in the game already that I totally missed.

I would like to help if I can. Where are these Folders, to be clear, are these in My Library > Purchases, or did you mean under the Journals tab, or as a third possibility do you mean folders in the Pages toolbar? Also can you give the name of some of these Add-Ons, and/or a screenshot of how it looks in your Roll20?  The top fastest way to access any Maps from your Art Library is .... type a matching keyword in the search bar at the top of your Library. By the way if you aren't sure some good keywords to type, load that Product from the Roll20 Marketplace and look at some of the keywords in the art packs you like. Usually once you get familiar with the keywords on your favorite items, this is the fastest way, but there could be other approaches too. 

The pages toolbar. The addons are specifically Tessa presents map packs. If I could just auto alphabetize this folder rather than manually sorting would be the dream.

Good point, there isn't a way to Sort your Pages toolbar by the Alphabetical names of the pages. I understand the Suggestion that Roll20 could add an Alphabetical sorting in the Pages toolbar, we just don't have that feature right now.  Also you already know the techniques that you CAN do. You can rename any of the Pages to anything you want. You can put any/all of them into Subfolders that will appear on the left. You can word-search in the big wide searchbar at the top to isolate any Pages by-name if you can remember the name from memory. This might save you a lot of time against alphabatizing them, if you can regularly narrow them down with the Search bar.
