Unhide by Select

This script allows you to unhide hidden objects by selecting them via mouse click or via Select From Scene dialog(H hotkey).

How to use it:

1) run the script - all visible objects will disappear. In the viewport you will see all hidden objects. If the script is assigned as a toolbar button it will stay pressed.

2) select the objects which you want to unhide.

3) run the script again - in the viewport you will see your original visible objects + the objects you have selected.
