I do keep separate vaults, but to separate contexts instead of for organization. For example, I dont want to see anything that reminds me of work when im planning my next rave. I keep one vault opened in VSCode and another in VSCodium, so I can switch between them with a single keypress instead of typing an address in the Dendron:Switch Vault function. This can be pretty useful since my girlfriend sometimes chats about weekend plans while I'm studying, and I just press a button and write down the plans in the other vault. Perfect capture, no friction.
