Thought I’ve seen this somewhere where this was possible (maybe using markdown). In scrivener, tinderbox, and most markdown editors, you can select multiple documents and see their text content all at once. Currently in DEVONthink, highlighting two text documents will only show the documents themselves and not their content. A markdown document will show a TOC where you can browse the document by its sections. I recreate the headings as groups and pane documents for ease of manipulation in my tagging system. I have seen a discussion where selecting multiple documents (involving some markdown scheme of some sort) would reveal all the textual content within them. Am I dreaming marbles here, or is this actually possible?
This isn’t supported yet but we’ll consider this for future releases (3.x or later).
I vote for this feature to be included.
