+1 from me as well. I think that once you have done the first login via Twitter/bsky/etc, you shouldn't autosync by default to twitter but leverage the "local" typefully account for key data (ex. the name for the newsletter/emails I get).

Definitely needed now, as X deteriorates it’s no longer the default platform for many of us.

I even didn't realize that it's not possible. 100% should be a must have, why limiting the app to this requirement. +1
