And as for ETA... Oof. Unfortunately my current fiat responsibilities are taking up a lot of my coding time, so progress is so much slower than I thought it would be. Haven't had the luxury of being full-time on SeedSigner since late last year.

However, some of the work I'm doing now in the test suite is actually helping to pave the way for the MicroPython code to move forward. And the next big push on the MicroPython side will/should/hopefully be a gigantic leap forward.
