Hi Cyril,
As I continue to play with this keyboard app, I have learned to appreciate its many features. It took me a while to get used to the punctuation bar, but now I use it all the time. My only complaint is that I am right handed, so my natural instinct is to use my right thumb to select punctuation. Plus that is how I get my period. If the punctuation bar could be right-aligned, then this would work perfectly - much faster and more natural than using your left thumb (in my humble opinion that is).
Thanks for listening and keep up the great work!
Nate
