Outlinely Express is a powerful free outliner for Mac
Glam Software has released Outlinely Express 2.0, a free version of its popular Mac outliner, Outlinely.
The new edition has all the same outlining features as its commercial cousin, with no annoying restrictions or limitations.
You don’t get any library management features -- new tools for storing and organizing your outlines -- but the program is very usable without them.
(Arguably Outlinely Express 2.0 is better than regular Outlinely 1.x, as it has a much-improved interface and many new shortcuts and productivity tweaks.)
If you're new to Outlinely, it's essentially a text editor optimized for outlining.
You already know how to use the core features, entering text, changing font and styles, search and replace, undo/redo, and more.
But the program builds on this with many outliner-oriented features, like creating lists within lists, dragging and dropping to reorganize them, attaching notes and links, zooming into any item, collapsing and expanding to hide/remove detail, and more.
Your outline may then be exported to OPML, PDF, Microsoft Word, RTF, HTML, Markdown, and plain-text formats.
Outlinely Express 2.0 is a free app for OS X 10.10 or later.
