Totally agree with most (if not all) of this thread.

I imagine that the guys at FS might have kicked around the idea of
implementing a better way to do mouse nav at some point in the past.
Curious of how well it would work since in order to do a VoiceOver
type touch based interface, all of the applications and its associated
controls would have to actually report a correct bounding rectangle.
That means app's written in win32 all the way up to WPF.  God knows
Mac OS has had problems with just one framework to worry about.

Also, does NVDA keep the entire accessibility tree in memory?  You
would have to "grid" up the bounding rectangles of every control on
screen--potentially from different processes.

I propose that someone tries to build this feature--UI Automation is
pretty easy to work with and building such a data structure doesn't
seem too bad.

I imagine this could be useful as you could view the screen like a
table of rows that can span multiple columns.  Then, a mouse drag down
would just drop you down a row.
