Inspired by Mark Levy I've started experimenting with
FreeMind (an open source mind mapping tool). The visuals are nice, simple, and flexible. There are lots of keyboard shortcuts, so I don't need to use the mouse that much. I like being able to easily collapse or expand sub-branches, spatially arrange them, use font sizes to visualize priorities. I still need to figure out what FreeMind's calendar features are capable of doing. I'd love to have an alternative view where tasks are sorted by deadlines.
