For me it was: 1. a similar interface across all platforms with similar features and behavior (android vs desktop text editing is a very different experience) 2. tagging/enhanced search 3. hyperlinks to other nodes and the Internet. This is incredibly powerful to me for nodes that are relevant in multiple contexts. You can put copy/paste the URL of any node into any other and viola, workflowy symlinks! 4. FOCUS. I have ~15k lines of notes in workfowy, but am still able to "zoom in" and focus on the content of just one note. That is super powerful for my productivity. A text editor with 16 spaces of indent and squished text to the right just does not do that for me. In fact, that will probably stress me out more.
