The relay counter (shows how many relays you are connected to) in the top left of home screen on Iris is really useful as well. Helps to stay on top of relay management.
Notifications also better on Iris (not sure if they're actually working on Snort atm 🤷).
Settings section on Iris needs some work (looks awful on mobile/cell screen).
I've been running all of the major in-browser nostr clients for several days.
IMO, the top two are iris.to and snort.social.
Iris ( #[0] ) best in terms of UX but I'm having to jump over to Snort ( #[1] ) to manage and send zaps/tips.
Two thing that make Iris better is that it remembers where you were in your feed when you go "back" and the feed itself is better (more Twitter-like) in terms of context within conversations.
Both brilliant though and being updated on a near daily basis.
🎩s off to all involved!
