Adding a search input to scope tab

[m-amr]

In scope Tab
1- Add a search input to developer can easily search for a specific controller.
2 -Add a search input to Models tab so developer can search for specific model.

I an angular app that a have a lot of controllers in the page and a lot of models in the scope of each
controller it is very hard to search for a specific model or scope

so i suggest to add a search input.
