But Flotilla needs to support local key signers too. Does it?
Discussion
I believe so
Login page has options for browser extentions, remote signers, and signer apps
That's different, that's web. And for that it uses Alby, nosx, Flamengo etc. The question is, does their desktop app support locally installed key signers?
Wouldn't that be remote signer option?
No, a remote signer is usually a piece of hardware, like the one from lnbits (https://shop.lnbits.com/product/nsec-remote-nostr-signer )
This is using nostr connect though, right. Pretty sure that's the same method as the remote signer login option.
