Is there going to be any non-views implementation for this? If yes, update
comment. If not, perhaps keep this in views?

No non-views implementations. However, the View prefix is not actually views
related. It basically is the "thingy" that supports touch base selection and
editing of text. I renamed it to "TouchEditable"... any better?

Sorry.. I make mistake. RWHVA will implement this for the webpage. So there will
be a non-view implementation (which was one of the reasons for this move).
