Cross Referencing capability

This request originated from the Help Topic I posted re "Sprite Renaming".
It dawned on me that if one cannot rename certain objects globally, then maybe a cross referencing capabiliity listing the use instances of the object in question could be of great benefit.
Maybe the JS gurus of the forum could whip up a block that would take a name as input and spit out all blocks using it.

That's a good idea for our (eventual) debugger. So, yes, I agree, but don't hold your breath; it's a long-term project.
