It IS an outliner. I tried using outliners back 10 years ago and became frustrated with options available. There were no good online outliners and the best desktop outliner, OmniOutliner, is only available for Mac. I tried a bunch on Windows but they were really buggy or didn't meet my needs. Then Workflowy came out and just worked.
