Using nested collections

[tpluscode]

Do I get it right, that nested collections only really work when all files are called index.* and their path serves as the collection.

I have this example structure, and a similar in a much bigger existing site I try to migrate to decap.

docs/
├── bar
│   ├── child
│   ├── bar.de.md
│   └── bar.en.md
├── foo
│   ├── child.de.md
│   └── child.en.md
├── foo.de.md
├── foo.en.md
├── root.de.md
└── root.en.md

I find that docs/bar and docs/foo do not appear as collection (no index?)

Most surprising thing that happens is when I edit docs/root and change the path to baz. This disrupts then entire collection completely

docs/
├── bar
├── baz
│   ├── bar
│   │   ├── bar.de.md
│   │   └── bar.en.md
│   ├── baz
│   │   ├── index.de.md
│   │   └── index.en.md
│   ├── foo
│   │   ├── child.de.md
│   │   └── child.en.md
│   ├── foo.de.md
│   └── foo.en.md
└── foo

What in the world happened here?

1. Everything moved to docs/baz?
2. The file I edited actually became docs/baz/baz/index.*.md and not the expected docs/baz/root.*.md
3. And decap-server died with Error: ENOENT: no such file or directory, rename '/path/docs/bar/bar.en.md' -> '/path/docs/baz/bar/bar.en.md'

Wouldn't this entire feature be some much easier if it just worked like a regular editor with directories and files?
