If you like to visualize your projects and tasks with mind-mapping, like
to work with an interactive GUI, and don’t mind proprietary software,
you may like The Brain. You can see how it works in this video. It
appears to be an excellent and well thought out product.
But I’m not here to shill for The Brain. I mention it because it’s the
inspiration for a very nice package by Erik Sjöstrand: org-brain. It’s
a concept mapping application built on top of Org mode and Emacs. It does
the same sorts of things as The Brain but from inside Emacs. If you
prefer keeping your hands on the home row to clicking and dragging on
a GUI you should check out org-brain.
You can get an idea of how org-brain works by watching Sjöstrand’s
video demonstration of it. To get the most out of the Sjöstrand’s
video I recommend watching The Brain video first because it helps
clarify the problem both applications are trying to solve and how they
go about it.
I don’t think my mind works in a way that makes mind-mapping a natural
fit for me but lots of people I know and respect make it an important
part of their workflow. If you’re one of those people, you should
definitely take a look at org-brain.
