This is awesome! Especially with qmk support. I'm in!  

A couple questions
- is this top or bottom mounted?
- will you offer the option to buy additional plates and pcbs? 
- what type of plates are offered? Brass, ano, acrylic? 
- day other layouts are supported? Split keys, bottom row, etc. 
- will there be any indicator lights? 
- do you have an estimated price?
