Snap options (as Photoshop grid options)

Hello!

Could it be possible to add an option to "snap" objects on the grid (as "magnetic" grid options in Photoshop and Adobe tools)? And/or "snap/align" them together? 
It's already possible via "Align" and "Step and Repeat" but that could be good without menu panels, in the main view directly, "on the fly".
Thanks!
