Plain text alternative to Scrivener's "Scrivenings" view and it's ability to rearrange and order files?

Ulysses and IAWriter have something like this. See this thread:

Scrivener, Ulysses, Obsidian Oh my!

Ulysses has a similar feature called “glued sheets”. Not quite the same in that while separate files are used they appear while editing as one. That said, you can write them independently and later glue or merge them for export.
