I’m finding OO6’s new ability to have the same outline open in two different tabs or windows incredibly useful. I can, for example, have the unstructured notes from a meeting in one window, and use them to update information and action items in the second window. I love how the outline state (what’s collapsed or focused) in each window can be independent.
For a long time now I’ve “run my life” off OmniOutliner. I keep massive amounts of information, history, and action items relevant to both my work and personal lives in it. It’s perhaps the most important software I use. The upgrade to V6 for me has been problem-free. Thanks for all the work you put into it!
