It reminds a lot of NXT - is HEAT built on top of their codebase?

I would like a README-user.md somewhere - which explains the very basics how to use it.

E.g. When I open the wallet at  http://...:9001/dist/#/login
I see a prompt for typing in my "SecretPhrase", but no "New account click here" button.

Can I use just ANY SecretPhrase? Trying that now.  How many letters max?
This looks like my account number:  #15806825503205248904  
Please send me some HEAT to play with, thanks.

Is it wise to show the SecretPhrase as cleartext in your input field?

Is the "Load BTC" functionality working?

Thanks!
