[FEATURE REQUEST] Add search to the import dialog

When I want to import something from a large multi-featured Asset, like let's use "Standard Assets" for example, there is no way to FIND a specific file, thing, or name. Just add a search field at the top that filters results from the package. Simple as that, and should work like the Project or Hierarchy panel search field.

Use case:
You bought a giant texture pack asset or music collection asset and don't want to import them all. Would be nice to be able to just type "grass" or "spooky" and see only related files...

 

Bumping this Feature Request because today, I again wanted to import only a subset from the Standard Assets (the lens flares) but it's arduous to FIND them when I can't search through the package.
