Congrats!!! It's looking great so far, love the low bandwidth aspect.
My Lemmy instance seems to have been abandoned, and it's been slowly losing functionality over the last few months. So, I've been begrudgingly trying to decide on a new one for when this one fails entirely... Piefed seems like it'd be a great choice, except I'll definitely need to wait until it either works with a Lemmy app, has its own app, or at least has a PWA. Anyway, great work!! Lovely to see multiple interoperable platforms shaping up.
Oh weird, I know where that option usually shows up for me (running Vanadium browser on GrapheneOS), but it doesn't seem to be there for Piefed?
EDIT: Nevermind, sorry! I think they combined the "add shortcut" and "install app" buttons in Vanadium, got it set up now.
