OK, this is nice. I've tried (and failed) to use Obsidian in the past because I have 8000-9000 Markdown files with frontmatter metadata and nested folders that I just can't get it to work with (they are typically called index.md in a nested folder structure, with separate sections and media assets in the same folder), but I also use Xmind extensively for my personal projects, so this has tickled my fancy.

As long as I don't end up with a single folder with hundreds of files, this seems interesting enough to check out.
