The Omni Group just updated OmniOutliner 4.1 with several useful new features:

• Row padding control has been added to the standard feature set.
• There is a new set of colored toolbar icons. (Purists can switch to Graphite appearance in System Preferences to use monochrome versions of those icons.)
• The Pro version now allows you to link to rows to quickly navigate or reference other sections. To make a link, select a row and use Edit > Copy As Link. Paste this where ever you’d like to make a hyperlink to that row. I often use OmniOutliner for witness examination outlines and deposition outlines. This new navigation trick will be huge for me.

The app also got improved Word export and other nice interface tweaks and attachment support. I’m happy to see the Omni Group giving my favorite outliner further love.
