That was supposedly the best front-end we had, right? Sad to hear--I hope I can become good enough to help revive projects like this.
On a sidenote, what other frontends are to be used in the meantime? I'm hoping one of the few is still being maintained somewhat
Not to advertise, but you could try Photon. It's what Tesseract was forked from wayyy back as me and the tesseract dev's philosophies split.
It's more opinionated, and features are carefully organized compared to Tesseract where plenty of shortcuts and links are given (which isn't bad at all, just targets different preferences).
You are on PieFed.social, so you do not have "frontends" like Lemmy does, you (we) have "themes" - go to Account -> Settings -> Themes, like Trans Pride, Card Shadow, etc. I use "PieFed".
