Godot Hider Node 
Sick of having nodes you don't need all over your scenes ? You don't want to see them all but you don't want to have to toggle their visibility all the time ? This is for you ! Add it as a child to a parent node and that parent's children will only be visible in editor when you select a node inside that parent's subtree. + other similar behaviors. It works in any scene : 2D, 3D, Controls,...
Simple to use :
- Add the Hider to a parent node
- Enable the Hider by toggling the enabled property.
Now, all the nodes in the subtree, starting from the Hider's parent, will be "hidden" when you select a node outside that subtree. They will be shown again when selecting a node of that subtree or the parent node.
Nodes are hidden by changing their modulate value. However, the Hider stores the previous modulate values in its saved_states property, which is reverted back when the node is shown again.
It has a bunch of bonus properties to make your workflow even better, everything is detailed in the documentation
