Widget Scripts UX

When creating a dashboard that utilises a lot of JS I am constantly finding myself 'editing' widgets just to gain access to the 'Edit Script' button.  There is also no way of indicating if a script exists other than 'editing' the script to check.

I think the UX could be improved by:

• Moving\Copying the JS Edit Widget script to the Option menu on the primary dashboard design screen.
  
• The "Peak Script" option could open a preview of the script on mouse over.
