From MacroView DMF/Message 8.9.491 and later A ‘Collapse Tree’ option is always accessible in the context menu.
When the tree is expanded in a lot of places and can become very long and difficult to navigate. Previously you would need to scroll all the way to the top of the tree view in order to collapse the tree by selecting the tenant node and using Refresh.
Each tree level contains the 'Collapse All' option
Folder/Document Set level
Things to note
The entire tree will collapse not at the level you selected.
