Was browsing and I thought that maybe having the option to put characters in folders would be nice. Like, having a folder that could be labeled "test builds" and you could put your test builds there or "campaigns" for your characters that are in campaigns if you are in multiple? Idk, I just like to be organized and be able to keep certain character stuff together instead of having to scroll a bunch or sorting things out ya'know?

It’s on their  list, and I agree it would be helpful. If you are using chrome on a computer, you can install the beyond help extension. One of its features is character folders. 

This will be awesome when they finally implement this feature. In the meantime, the way I do it is to stick the characters in campaigns with those labels and navigate them through the campaigns page. I don’t know if that will help you at all, but it is a workaround until we get folders.
