Suggestion for the Natrium guys... (private key / mnemonic phrase related)
I just got done showing my coworkers how fast Nano is, and they were blown away by it. However, English is not their first language.
However, the one complaint that they had was the lack of customizability with regards to their mnemonic phrase. I personally like the idea of keeping a 12-word mnemonic phrase just because I can memorize it easier than I could a 24 word Mnemonic phrase.
Just my two-cents.
