Can you store multiple keys? If so, that would be incredible. Hamstr.to (or whatever it's new name is) is the only Nostr client I know of that allows for easy switching between accounts (but when I looked the other day there'd been no updates to it in the past month - so not sure that's a long-term good option).
Handling multiple keys is huge for people who have to manage multiple brand accounts. (Or even a personal account and an "alt" account). And it's a lot less wasteful. Right now you log into "account 1" pull all the data for that, then logout and login to "account 2" and it has to pull much of the same information all over again.
