Yeah just found it today and I quite like it so far. Had been using Jerboa but the after v0.0.37 that was pushed out made it's just crashing on startup since I was logged into lemmy.world. However I would like to see an option to not merge the feeds of all logged in accounts. I prefer a UX to switch what account I'm viewing with and see only the subscriptions of the selected account.
Apparently my desired feature is already present. From the Home tab the Subscribed/Local/All button expands to let you pick which logged in account to show.
