Haha, completely agree with this sentiment. By far the most attractive thing about this for me is being able to check my phone and immediately assuage that "Oh shoot! Did I lock the front door?" feeling.

It's something I've been thinking about a solution to for a while. One of these days I'll get around to making a key cover with a simple mechanical display of which direction the key was last rotated. Cool idea, right?
