I use Workflowy as well, and Fargo didn't feel quite as convenient to me. One thing in particular I noticed was that moving an item to the same level as its parent is easier in Workflowy.

So I'm sticking with Workflowy for now. I just wish it allowed me to add multiline leaf items!

Workflowy is great.

In Fargo, if you want to move an item to the same level as its parent there are four ways to do it:

1. Shift-Tab.

2. Cmd-L.

3. Drag it to the left with the mouse.

4. Choose the Move Left command from the Outliner menu (useful on tablets and phones).
