Open library default, when open directory opus

Good morning, I am a new user.
when I open directory opus, I want the library to open as a standard, and to open it completely in the folder tree. is this possible?

Ton

To make the default lister open in a library, go to the library and then use Settings > Set as Default Lister.

For the folder tree, turning on Preferences / Folder Tree / Options / Expand selected branch will expand the library itself, although only to one level.

Yes, this was the solution. :grinning:
Thanks.
