Collapse all categories in project browser

[HVAC-Novice]

There is an idea request about this, but i wonder if someone has a good workaround.

In the project browser i often end up with my sheets, view categories and family categories expanded. I design in multiple disciplines (A, M, E etc.) and jump forth and back as needed. so my project browser often has many views expanded, sheets expanded, and family categories expanded. this clutters it up quite a bit. 

I know I can collapse each sheet or each family category by selecting it and clicking the "+" or hitting "-" key. But I have to do that for each category. 

But what I want to do is collapse all family categories (or sheets) at once and then just expand the one I currently need.  That way I don't have to scroll so much through my project browser. 

any ideas how to improve my workflow?

Right click on the folder and then select collapse selected or collapse all

Thanks. But that collapses everything (families, sheets, views etc.)

I was hoping to collapse all families, but keep the views expanded for example. 

I guess the best I get is to collapse all and then selectively open what I need. or i make sure to always collapse an item after I'm done using it. 

Well, would be nice, but isn't the end of the World.
