Okular: add option to collapse opened chapters

Hello everyone,
I hope I’m posting this to the right section, I’m new.
On Linux Ubuntu, when I open a pdf with an index, chapters are exploded by default.
When the book is very long it’s painful to go through it by scrolling. I wish there could be an option to collapse all the chapters in a short list when you want to move fast. On Windows it seems that by default chapters are not expanded. Do you think this is a good addition?
Thank you!

if you right click in the side bar and choose collapse all then everything is collapsed.

are you asking if this can be the default whenever you open a document, instead of expand all?

i don’t think that would be a good default but, as an option in configure, it might be a good feature request for the Configure Okular > General tab, either under Appearance or Program features

you can make a “wishlist” feature request ad bugs.kde.org
