Otherwise, if you don't want the tree to be unrolled every time, you have to go to Tools/Options/System Options/Feature Manager/Unroll the selected object in the view.
I'm thinking about something, there's an original keyboard shortcut (I think), which is Shift + C and which brings the tree together. (Tools/Customize/Keyboard/Others-Gather All)
It can be an alternative if the option to scroll down the tree seems useful to you.
