Me personally (using Haven) I'd really like an WebUI for management (storage and stats mainly, like seen what's in Blossom and easy delete something with classic lists and checkboxes + eventual regex/query search) and a client built-in so one can deploy a single application and have all setup in a single shot: "just install Haven, go to localhost:port and start reading, publishing, managing your Nostr garden", the need of separate stuff kill newcomers interests IMVHO.

The client itself well, could be very rich, like a public blog face (long form), a Reddit/Lemmy-like face (short form), a contact manager for Nostr as a digital identity, a chat UI, tomorrow adding VoIP as a module maybe, than some long form became a Wiki, some short form tasks with a management UI like Vikunja and a step at a time "the modern personal web" became Nostr.

A long journey the humanity really need :)
