I use it as a desktop browser client which is running as a self hosted app on one of my private Start9OS DIY devices.  Then setup/config nostr accounts and off to the races like a nice desktop app.  So instead of using one of the also fantastic public web Nostr websites....I can now use a locally hosted one.  So playing with it recently.  I have been trying to also use the Start9OS nostr relay app...but I'm having issues with my client apps reaching it via the TOR and even internal LAN wss/URL addresses....so no luck yet on that as a nostr backup relay for all my nostr data.
