I would like to hide many items in the Outliner by grouping them and then collapsing the group.
I realize the Outliner can display only Groups, but those groups are functional groups that affect the way, for example, animations work.
The kind of groups I'm wanting to create are solely for the purpose of reducing visual clutter in the Outliner and won't effect anything else.
I saw this question was asked before, but none of the answers solved my problem. (How can I organize the outliner with groups?)
Does anyone know of any solution?
