Following previous dispatches here and here about the endless, quixotic search for the ideal outlining program, many people wrote in to sing the praises of a Windows-based program I had not been aware of: InfoQube, or IQ. (Hardee-har!! I get it!) Sample testimonial note from someone who identifies himself as "a highly satisfied user" and who doesn't appear to be connected to the company:
"I'd like to let you know that InfoQube (IQ), while still a bit unknown and not out of beta yet (but soon to reach v1.0 ), is a very powerful Outliner too!
"In my humble opinion, probably the most powerful and flexible out there. Really. I have been using it for the last 2 years, doing incredible things with it... Not only does it do outlining, but it also has a calendar, Gantt charts, pivot tables, etc.
"It's not your typical software : it takes an open mind and a bit of reading (not that much!) to understand its principles. These small initial efforts are quite rewarding, that's for sure!
Have a look at it (Download), and feel free to ask questions on our friendly Forum. ["Our" = user community, not speaking for the company itself] Pierre Paul Landry, our IQ talented, dedicated and friendly developer, answers many questions himself."
Here's a thematic illustration from the company's site, on the "Qube" theme. (Click for bigger.) Disappointingly, the actual program is confined to normal 2-D computer screen displays. I have not yet tried InfoQube myself, but I received enough mail from people who have that it seemed worth mentioning.
