Also note that having max undo's set to the default 100 will definitely slow P7 down, as it has to write to, and reorder the undo's every time you change just about anything.

Turning it down to something like 20 or 40, allows you to take advantage of it, without creating a drastically noticeable slowdown in responsiveness.
