"Show items of this screen" should not always display

[GnunuX]

If we do not select area, the like "Show items of this screen" didn't work (not lon/lat set so no href).

This patch (maybe not better solution for this issues) toggle on this like want user has selected a location.

Could you provide a pull request for that. Also using the version 2 layout.
