Aligning Work Planes to Model (was "Work Plane Visibility" in Wishlist)

[funkman]

I would like the Work Plane Visibility have several more options available such as:

1. Specify at specific intervals darker grids appear (eg. every 5th grid to appear darker),
2. The "crop region" boundary being able to snap to the edge of a grid,
3. Being able to specify a non-rectangular extents for the grid,
3. Being able to align elements with the grids.

3. Being able to align elements with the grids.
While the Align tool won't select the Work Plane grid lines, note that the second pick of the Move tool does snap to these grid lines. So, if an element is already parallel to the grid line, you can line it up exactly using the Move tool. (I understand that this is more picks than using the Align tool would be.)
