The registration process should ensure maximum possible security measures. I propose, users should
use fingerprint scanner as default if it is available. If not, we should guide the user to create
a strong, multi-word, pass phrase. Before showing user the recovery phrase, he should
be educated on how to secure and store his recovery phrase.

I think giving the users option to change their fees should be implemented together
with an estimation of confirmation time. Exodus requires users to use high fees
to get fastest possible transactions. Some people like, but some hate it. The
speed is not always the priority for everyone.

14. I propose a minimum of 2 themes for people to choose from.
Ideally, Pillar can have more contests for designers to create many interesting styles and themes.
People on Twitter seemed to like the dark theme more. Many expressed their desire
to be able to switch themes.

Survey showed, having many different coins / tokens, is something users desire.
I was exploring how to show as many different currencies as possible, while maintaining
simple layout. Users should have an ability to customize their UI and
dragging their most used coins to the top. They can be sorted by the
fiat amounts stored in each of currency by default.

your consideration.
