Cool... but "randomizing function which integrates hardware entropy"
is nothing new or special. Using hardware entropy has been the standard
for a long time and is part of most programming languange implementations.
It is cool because there are no convenience/security trade-offs. It is both the most convenient paper wallet generator
and the most secure paper wallet generator.
I would argue that convenient is not always good when trying to secure your funds. If you are doing something that is convenient for you then you may not take every necessary precaution necessary. Even if this generator is secure, by utilization convenience you would be more likely to bypass other security measures that are necessary.
