I hope this gets implemented, and I hope Apple doesn't receive a patent.
Agree. While this would be a nice feature, it would be a joke of a patent. And seriously, the solution to frivolous patents ***IS NOT*** to preemptively file your own frivolous patents as Apple is doing here. The solution is to overhaul the patent system. There are presently millions of US patents in existence, and the dirty secret is that huge numbers of them them are frivolous and obvious, especially in the case of software. Remember, Amazon's 1-Click was patented!
In addition, there are like 3 million genome patent applications right now! This is a total abuse of the system. Patents are an antiquated holdover from the 18th century and simply too ill equipped and too easily abused by today's standards. Time to bring the entire conceptual framework into the 21st century.
