From quick googling, there&#x27;s some discussion where people are suggesting alternatives: <a href="http:&#x2F;&#x2F;www.outlinersoftware.com&#x2F;topics&#x2F;viewt&#x2F;2200&#x2F;5" rel="nofollow">http:&#x2F;&#x2F;www.outlinersoftware.com&#x2F;topics&#x2F;viewt&#x2F;2200&#x2F;5</a><p>Personally, I haven&#x27;t ever used PC Outline, so I don&#x27;t know its features, but from many free outliners I tried I liked the Noteliner. Unfortunately I couldn&#x27;t find a replacement on Linux (and I don&#x27;t have time to learn Emacs + org-mode)
