Hmm, while the [new]label on #Fedilab is nice, it disappearing as soon as I click on the favourite button, causes an #UX annoyance as that shifts the buttons one to the left again. So, instead of tapping 'favourite' followed by 'boost', I ended up unfavouriting it again instead. Maybe put the [New]label on the right side perhaps?
I use the compact display mode yes, but I can't find a setting for the New indicator label? Besides, I like the indicator; it's only the changing of buttons directly after an action that throws me off. :)
