In Blender when you unhide object, everything is selected, it's not always practical, so I made this little addon to reveal all hidden objects and keeps the current meshes selected.
It works in Object and Edit Mode:
If nothing is selected, nothing will be selected.
To keep the selection you need to have one active object.
The addon uses Alt + H, so you have to deactivate the current shortcut in the input tab preferences.
