Search and replace in Name Mapping

That would help a lot! 

Well, it is already done )

Searching and Replacing in Name Mapping Editor

We have tried it before and the search does not find items that I am looking at on the screen and therefore know that they exist.  I assumed the search did not exist in there, instead I should have assumed it was a defect?  lol

Agree on this one - a Google style 'search as you type' to narrow down results in the Name Mapping and Aliases hierarchy would be really helpful.
