OK Tokodon it is.
I had a brief look at #Tootle which I installed a while ago but didn't like the GNOME like UI. So that is now gone.
I also tried #Tokodon a while ago but preferred the old Mastodon web UI to it.
Now, with the new Mastodon web UI Tokodon is the easier to look at and use.
Cue the Tokodon UI changing to match the "great new Mastodon" look.
Spoiler, Tokodon already has roundals instead of squared off icons. Sigh.
