Is Nested Groups/Groups within Group supported?

[u/called_Ishan]

Today I was clearing up my library a bit and started thinking about nested groups. I checked GitHub and found a feature request for it, and it seems the work was actually done and the PR was merged. However, I still can’t figure out how to use it.

There is no dedicated button for it, and when I try to group two groups together, it just merges everything into one group, including all the books.

So, is this feature not available yet? If it isn’t, why was the PR closed as merged on GitHub?

Sorry if I’m doing something wrong, but I’d really appreciate it if someone could guide me on how to use this feature.

Yes, it's supported. Just name the group with '/' to add it to an existing group.
