Multiple text files in the same pane


I use atom mainly for editing long markdown documents. I tend to split these documents up into several smaller files for organizational purposes, but it would be great to be able to see all of these one after another in a single pane, separated by a horizontal line or something. This would be awesome for proofing, or easily referring to earlier/later parts of a document.

I understand the limitations – mainly that atom would have to work out which order to display the documents in – but since I name the files in alphanumeric order (so that when I compile them I can just use pandoc * -o $file) for me at least this would be fairly simple!

I don’t know if this would be easy to achieve with a plugin, or if it is already possible?
