Currently if I hold Shift while drawing a shape to "snap to grid", I have to drag the mouse until the shape becomes large enough to snap to a grid square/hex. Otherwise the shape is not drawn at all. I would suggest that "snap to grid" shapes default to be at least one grid square/hex in size, that way you can just do a single Shift-Click for single grid size shapes(or drag for larger sizes). It would be faster when the user needs to put out a large number of single grid sized shapes, and more precise since repeated clicking greatly reduces or even eliminates the the frequency of "over dragging" when swiftly drawing the shapes. Also, "under dragging" to a less than one grid square/hex resulting in the shape not being drawn at all, seems like an un-needed failure state.
