Nunchuk is doing really great stuff on multisig UX. They have an integrated chat so if you do multi-person multisig, you can share and sign psbts right in the chat. You get a little button to sign right in the chat! Its super slick. Their NFC support is great. Ive been playing with a tapsigner and a satscard for a few days and it works really well. And they support signet! Awesome project.
