Have "Drag and Drop" default to unselected, rather than enabled.

Drag and Drop is a great and convenient feature when used deliberately. It also is one of the most risky features when it triggers accidently.

I spend most of my time scanning (scrolling) left/right/up/down in the expanded view looking to make adjustments. Like many others have said, a scroll can too easily become an accidental drag and drop. 

I would far prefer to check the box in the top right when I want to drag and drop vs unselect it when I don't.  

This is likely one line of code that needs to be updated to default to deselected, rather than selected. 

Please do this. Others have asked. It's a problem with usability.
