Snap-and-go allows aligning and not-aligning objects
Here is what to
1. Traditional snapping:
Align the mud-colored rectangle with the two green rectangles
(target location marked with gray frame).
Now try to place the mud-colored rectangle close to the green
rectangles without aligning them: it is not possible (users need to
turn snapping off in order to be able to do that)
2. Use the radio buttons to switch to snap-and-go. Repeat. This time
you can align and non-align the objects.
