Looking for a simple outliner

Question

Back in the day i used OmniOutliner a lot. Is there something like that for GNOME? Google suggested me Gnome Outliner and a friend of mine mentioned TreeSheets.

But is there something else?

Answer 1

If you feel comfortable with vim, I suggest VimOutliner.

Answer 2

For GNU Emacs there is also an Outline Mode. You can activate it with M-x outline-mode. A good example is the Emacs NEWS file (open it with C-u C-h C-n). Different header levels are marked with *.

* Level 1
** Level 2
text between
*** Level 3
more text

You can show all by pressing C-c C-a and show only headings with C-c C-t. The manual has a more detailed description.
