Thanks for taking the time to reply. That all makes sense and is what I would have hoped to be the case.
I see below too that you've spent a lot of time on this — it definitely shows. I am already finding the keyboard shortcuts and text manipulation to exceed my expectations a web-app that's based on a giant free-form textbox.
A couple comments on the iOS app. I am running iOS 8 so maybe these are known issues awaiting an Apple approval... Both the keyboard and horizontal position in the stack seem to get stuck often.
An example to cause this would be to tap into an existing item while the keyboard is up to reposition the cursor ... if I pan right/left it'll start to pan the view left/right along with it which will persist once I'm done. Swiping left/right after this will keep this offset. The keyboard too also sticks to a certain degree in these position changes.
