Vault Virtual Folder Views ("file explorer" content organization)

I am trying to discover what exists for virtual-folder navigation and management views that follow the pattern of CHM/Help file authoring systems, or Visual Studio Code C++ source views. See this “Contents/Index/Search” panel example from Directory Opus 12.

Basically, they allow one to create a MOC that is hand collated (TOC). Much like one would see in any book, manual, guide’s tree view for navigating the content.

Has such a content organization/publishing “file explorer” type of pane been authored experimentally or otherwise?

Hopeful as I learn the capabilities of Obsidian
