[1.5] Align desktops to 3x3 grid?

[f4te]

Hey there, i'd like to start by saying this is an amazing program! I've yet to figure out all the features, but one thing i've noticed is that it doesn't seem to allow me to align the desktops to a grid- so that i can move from desktop 1 (top left) to desktop 4 (middle left) just by moving the mouse down. If this is possible, how do i do it?

Cheers, and thanks again!
