Cannot search meshes in navigator or select them from viewport

Currenlty you cannot search for meshes or select specific meshes from the viewport. Because of this working with complex models is very slow and difficult.

Example situation from Sandeep:
Needed to delete front mirror, I cant select it from the viewport, don't know where it is and don't know which nametag it uses. had to click each of the sub mesh and it has 118 sub mesh. workflow: open the model in Blender find the nametag for the mirror come back to qtds and look for that name.

We need a more user friendly way to navigate the meshes.
