Are there any packages as powerful as org-mode for emacs out there? Some of the features found in it are:
- Pure text
- Literate Programming
- Foldable headings
- Clock (control time spent in each task)
- Task state (TODO, DONE, etc)
- Exporting to publishing format
Also, in a side question, how hard would it be to create a linear scrollable view with multiple different packages controlling each part of the view? E.g.: having a pdf rendered by one package and just after it source code and then a image where you can smoothly scroll between them as if they were a single file.
