> Traverse is a macOS outliner with a focused Writer view, flexible outlines, column browsing, attributes, filtering and portable OPML files.
I really love this app. It's a powerful horizontal outliner (I was a huge Tree fan back in the day) with a plain text (OPML) file format and a very complete feature set. I don't think it's as scriptable as Bike, but the GUI is very complete.
Plus, it can stream to Marked 3!
