I don't know how many people play games entirely via writing, but having a large amount of characters/monsters makes the process of picking the correct NPC to "speak as" very inconvenient for the GM, and it's super awkward if you e.g. pick the wrong one and reveal the existence of another character by accident. The lack of folders and good navigation in the Archived bin makes archiving very inconvenient as a solution to this, particularly when you prep for the long term. If Roll20 can't improve the folder/archive experience in general (which would be great), I'd love to at least have a simple toggle, turned on by default, that determines whether a character appears in the drop-down selection for speaking as.
