(I couldn't find a thread for suggestions for the character creations) I'm a Dungeon Master and make a lot of character sheets through dnd beyond. I know at the rate I create that I have to scroll a very long time to find who or the multiple sheets that I need for the session. It would be really cool if we could sort sheets in folders we could name to help navigate the looooong list of characters. That's all :)

You could create a "campaign" for your npc sheets. At least then they'd all be at least in one group per campaign.

But, yeah, I haven't seen any way to create sub-folders within campaigns.

There are a bunch of different ways to sort your characters on the page -- newest to oldest created, highest to lowest level, alphabetically by name, etc
