Just upgraded to OmniOutliner Pro (OOP) last night. It's to die for. It's pretty well agreed that OmniGroup has the best OS X UI going. That's for sure. This could be the To Do List tool that works for me. It's so enjoyable to use. Remember how David Allen says that making GTD fun is half the battle?
Most of the cool stuff is also in the non Pro version but I thought I might want to export an outline to HTML at some point, and Pro does that really well. The upgrade is $50. That hurt a little but wow!
Outliner guru, Ted Goranson of About This Particular Outliner, loves OOP's UI and strong support of named styles for outline levels [Update: Named styles can be used and edited in OO but can only be created in OOP]. Me too. Every time I pop out at level 2, I get the style that I want. And I can change it if I need an exception. Here's what Ted says about the fabulous UI:
All this is wrapped in the Omni Group’s usual attention to user interface design. I think these guys are the leaders in Mac user interface expertise: their applications just feel more Mac-like than Apple’s. In this case, there’s all sorts of new user feedback: outline manipulation is, after all, a tactile experience. Like your first dip into Aqua, some of the indicators may seem garish at first, but the impression passes.
OOP has Folded Editing and a drawer that shows your main outline sections so you can show and not show pieces of your outline at will.
There's audio recording anywhere in your outline - little audio blurbs. Done to perfection. You click the record button and a little cute recording button appears in your outline where you are clicked an immediately starts in record mode. Just say something and click when done. Cool!
I don't show them in my screen shot, but OOP supports columns which will come in handy for sorting and grouping stuff for various GTD purposes.
There are a million outliners out there, but OmniOutliner Pro is spectacular.
