[Reposting from another thread]. Just upgraded to v7 (MacOS), and noticed the following sidebar behavior. With the disclosure triangle closed, you can still select the top-level item (for things like Notebooks, or Tags), and then the middle panel displays a full list of child items. But if you try to select Shortcuts with the disclosure triangle closed, you cannot do it, thus it won't display the child items. Seems like the behavior should be consistent, and it would certainly be helpful.
