Awesome thanks. I just flashed that repository and enjoy all the new features, especially the QR maker. I was wondering how to make something like a compact seedqr from seedsigner and you made it happen!

You can export Compact Seed QR directly after loading a wallet. Just go to Mnemonic-> Compact SeedQR. Swipe sideways to change modes to help you transcript your QR, swipe up to leave
