Whaddaya mean, you can't select an object if it's too big or too far away? What's the selection feature in the lower right corner of the screen for then? You absolutely don't need to click on the object itself. Oh, yes, that reminds me: The object tree! So, not a single long list of the meshes in the scene, but one hierarchically divided by objects: object one mesh one mesh two mesh tree object two mesh one_2 mesh two_2 and so on.
