When I was flyingthe other day, I tried out the 'direct to' function and it worked well. But, I thought it might be an improvement if instead of of just clicking 'select' and going straight to the route, I thought (especially if a bit turbulent)  it might be better for the first click to highlight the selection, so you can confirm it's the right choice, and the second click then selects it.  As you know it's easy in flight to hit the wrong button especially so for a smaller screen.
