Description:

Think is a Gnomified outliner. It doesn't do a whole lot at this
point, but can load and save outlines of text.

Think uses the Emacs outline-mode format for its files. It is a simple
format, and easily used in any text editor... I certainly don't want
to force Emacs upon everyone else. Indeed, part of the reason I'm
writing Think is so that I won't have to have Emacs running...

Tree preferences:
- tree title
- show numbering
- show priorities
- show completed items

Node preferences:
- title
- text
- action item (produces a checkbox beside the node, in the tree)..
this can also (for large projects) be a little meter that displays the
percentage done of a node... The percentages complete of branches are
computed from their leaves.
- priority

Misc:
- drag & drop moving of nodes, from branch to branch
- cut & paste
- promote/demote buttons to move nodes around
