I just use notedeck since it fully jntegrates nostrdb and has efficient (0 network data) account switching, i don’t switch accounts in damus iOS or have alts, so it’s never been a personal priority.
Damus iOS is open source and anyone can add it, but we don’t seem to get many contributors.
After I fix our web profile pages, add zaps and android support to notedeck, i will circle back to damus iOS to hook up nostrdb and account switching if noone gets to it before me.
