Question: How to Collapse All Items in Outline for Overview?

[mmngreco]

First off, thanks a lot for this amazing plugin; it makes my life easier every day ;-)

I have a small issue using the outline, and that is I'd like to be able to collapse all the items, usually to get an overview of the file's content without having to go through the entire tree. I've looked in the documentation and the issues but haven't found anything similar. Is this possible to do? Is there any workaround?

Thanks a lot.
