Adjusting the width of the left sidebar

Dear all,

I am using Logseq via the Mac App.
Content is in iCloud so that I can work with 2 computers, iPhone and iPad.

I would like to widen the left sidebar (Journals, Favorites,…)

It turns out that my Favorites (mainly individual pages) are longer than the standard width of the sidebar - resulting in a cutoff with … (e.g., Favorite title which i… (s long))

I am trying a light-weight hierarchy: “Framework - Components”, “Framework - Implementation” etc.

The problem is that the sidebar cuts already at the trunk level.

Is there some css needed?
If so what is it?

Thank you very much in a advance.
