Collapse expand notebook stacks that are in shortcut area

Being able to collapse/expand a stack that's in the shortcut area would help workflow. Thanks

You should be able to do that by right clicking on the stack and choosing the 'collapse stack' option.  Definitely think it would be easier to have a carrot or easier call to action to collapse these shortcuts, but if you want to clean up that shortcut sidebar, it's just a right click away.
