Finally a more interesting design! Congrats to your gf, I rarely ever see unique/creative ideas about the sat symbol.

I don’t think we’ll ever reach a consensus though. I think we’re gonna stick to just “sat”, similar to “USD”. The other ideas are imo too complicated or easy to confuse with other symbols and shortnames. You can see a conflict on BTCtalk too, some use sat, others use s, others prefer other shortnames which are less known. It’s a neverending conflict.
