* Support for Cold Storage spending from masterseed keys
Very good. Would be better if one could type master seed in the cold storage spending instead of copying it from somewhere else 
Ah yes, I use master seed QR codes, but we should (and will likely soon) add the ability to just type the seed.
I would like to remind about that. Also, could you add the possibility of sending to/from password protected version of stored (main) master seed?I don't see why I should type/scan master seed when I want password version if it is stored by Mycelium anyway.
There is no (or I don't know one) easy way to send to password version of master seed. I have to initialize Mycelium, or use some special tool to generate address.
