I figure that this might be a good place to post this suggestion. I use DNDBeyond for a few different campaigns and have been very happy with my membership for the entire length of time that I have had it. That being said, I do have a ton of character sheets created on this site. One of the most frustrating things about DNDBeyond in my opinion is that there is no folder option within your account's character sheet page. This would make my campaign planning and story writing much easier and ease some of my anxiety whenever I open up my character sheets; if someone would take it into consideration that'd be great. 

As an interim solution until they implement actual character folders, you can repurpose My Campaigns as character folders (as long as the character is not in a campaign already). My Campaigns is essentially a grouping of characters by campaign already, but you do not actually have to group them by real campaigns. You can name not-actually-campaign campaigns to things like "character concepts", "dead characters", "NPCs", "UA subclasses", "funny memes", "The Supreme Divine Imperial Order of Ultimate Elven Wizard Masters", or however you want to sort your characters.
