I think I may have just painted myself into a corner...
Is there any way to move a UI component built in Google's GUI Builder for a Google Spreadsheet script into another spreadsheet?
I've developed a GUI using the GUI Builder in a test sheet, but now I want to use it in a different, already existing working spreadsheet. I can't find any way to move it. If it can't be moved, is there some way to serialize and store the elements of the UI so that I can read those in from a new script in another spreadsheet. I'd even be happy with copy and paste as part of the solution (this is how I move scripts around, after all).
