[FR] collapse all sub pages should collapse all sub pages

[Ray0m]

Description

In left nav, using the right click "collapse all sub pages" should not hide all sub pages but truly collapse all sub and sub sub pages.

personal importance eval : 3/5

Impact

not having this ability makes navigation very uncomfortable - my team members are complaining of this app being "confusing" and them not knowing where things are and it's in large part due to the mess that left the nav bar.
