You can expand or collapse all with a context menu command.
And once we had that, we got another idea:
We can look on the names and find duplicates. If you ever use "Go To Layout" with name, you may have run into a problem with duplicate layout names. Our plugin selects all duplicate entries, so you can see which are belonging together.
And of course our contextual menu allows you to open the find tools, do copy and paste like the edit menu and show you how many entries are selected.
You can try next week in the version 12.3pr2 for macOS.
