I notice you changed the pattern on the private key obfuscation panel - any particular reason?
As a matter of fact, yes!
* On the front side, the obfuscation is now truly random, unique for every wallet. Important for defeating someone smart enough to be doing candling and looking for a "difference pattern" with the old predictable
* On the rear edge, the obfuscation is now simply more attractive. I use a flowery guilloche pattern instead of those colored dots. It's placed so that its most dense ink areas go right over the QR codes.
