Yes, I've been thinking about making in-browser construction of identities available as an option. There is nothing difficult about it in principle, but it sort of defeats the purpose of keeping the identity-securing keys airgapped. I may still decide to do so as a sort of toy-identity option so it becomes very easy to try it out. I first want to fortify the surrounding infrastructure, so it's more scaleable before I roll out an-easy-to-try option.
