[Snap to Grid]

Photoshop has a snap to grid feature you know (just photoshop costs and arm and a leg and a kidney), also the grids usually are not part of a picture, they are just on the UI. Snap to grid is really useful when you are actually drawing something yourself rather than just editing an existing image.

[Grid Maker Plugin v3.0 - Updated July 2, 2014]

Does this also have the ability to snap to grid points?

 

If not could it be added?

 

Edit: Noticed a post above, just to clarify, I need to draw something not position it, so I need to be able to snap to a grid point, draw a line, snap to another grid point, etc. So the PseudoSnap plugin mentioned would not help there.
