No problem at all; I'm sorry I didn't use the issue tracker directly.  I will do from now on.

None of those suggestions were show-stopper criticisms.  I think the core functionality of the app is perfect: a simple wallet, that doesn't require any effort to begin using it.  While I always love extra features, that core principle is what's important.  Anyone could have that on their phone and use it without any technical understanding of bitcoin at all.

In short: I like your app very much.  It's a permanent resident on my phone now.

Here's why I think apps like this are important: I could show this to merchants, and friends and not have to explain anything about block chains, transactions or anything else.  It's easy to see how this one little app could replace the credit card machine in the local newsagent.
