Mostly LGTM, however the calculator widget keyboard behaves a bit strange:

• on appear there's sometimes a black space covering part of the widget
• maybe also it would be good to be able to close the keyboard by tapping somewhere outside, currently cannot close it until I swipe to main wallet screen.

Right, this was hard to get working because there is a ScrollView nested in another one. I thought I got it to an acceptable state but retesting now it is very broken. Let's remove that commit from the PR and I'll give it another try separately.
