Actually it would max at 3 steps. For example: from middle top row to corner bottom row or vice versa... but enough nitpicking ;-)

Personally I'd think that this would not be a very useable solution. Hard to describe.... it would "feel" more complicated to search for a specific screen vertically and horizontally... something along the line of: "Heaven where am I know? top row? middle row?"
I think that it is more practical only to move in one direction in an endless loop.

Sorry if this reads a little strange but english is not my first language und expressing vague feelings or concepts is a little hard on me in english.
