Short description of error
Using the outliner of blender 2.79 and pressing on a parent object of an hierarchy in combination with CTRL+CLICK hides the whole hierarchy, including the children. Doing the same again unhides the complete hierarchy.
This is not working in Blender 2.8. Instead you can only isolate an object. But de-isolate is NOT working when clicking on the same object again. Hiding a whole hierarchy in 2.8 is impossible currently or I didn't found it yet.
This is really annyoing when working with a lot of object hierarchies in a scene. Please correct this.
Sometimes I don't understand why you are changing a really optimised shortcut system like it is in v2.79. But I have hope for the future... :)
