There does not seem to be a way to get your instruments boxes to "snap-to", or automatically line up other instrument boxes.  I am used to have this feature in Windows.  You have to manually line up the instrument boxes which is hard to do without leaving spaces between the boxes or having side-by-side boxes at different heights.  The "snap-to" feature makes your screen look more organized.  If this feature is already in the software, please advise how to activate it.
