I've just had another look at my mastodon instance's web interface for the first time in a while (I usually use Ivory), and the UI changed completely.
It's much darker and ... 'boxy'.
Not sure I'm a fan of the boxed look, to be honest. Has some serious retro feel about it to me.
Are the mastodon team cooking up a big overhaul? If so, then they are off in the completely wrong direction imo.
What do you think?
