We have a number of Product Owners who like to organize things from the Portfolio Tree level. In prior versions there was a button to expand all Portfolio Items in the column headers (it looked like a "+" sign). For whatever reason, that "expand all" button no longer exists... ? This is something that we would very much like to see put back in or made available again if at all possible. The contract all tree items button is still there (i.e., the "-" button), so why wouldn't you leave the "+" button? It's also on the Backlog pages as well.
