We've brainstormed some ideas on accessories for Batch 2 and Founder's Edition that we haven't been able to build on due to time constraints, but as we've grown we've had more time and resources to bring things like that to the market.

Keep an eye out for more on that!

Does foundation plan to follow most hardware wallet providers and offer accessories/backup plates etc? 
Great work on Passport and Envoy, don't expect you to do it all!
