I created a custom function but there is a bug that i want to debug.
The fact that the javascript on preview is minified makes life pretty hard.
Is there a way I can view a preview with out having minified javascript so that I can use the browser debug tools better?
Sorry, the script is currently encapsulated (to prevent script errors from interfering with the Hype animation - this is all too common) and there’s no way to get better debug information. We definitely acknowledge this as a painful shortcoming, and would like to have a solution in the future.
Nice idea but I doubt that will help since Hype is not open source so they will have no idea at guessing what the vars are named
Better than nothing! 
It's always good to offer an idea. Hence "Nice idea" so I am not sure I understand your point. 
Maybe it would have been better to put “slightly better than nothing”
