WorkFlowy just released a new feature called panes that allows opening various parts of your outline in separate vertical panes. While you could always manually do something with split browser tabs or multiple browser windows before, the panes feature is quicker/easier. Reminds me a bit of how BrainStorm allowed opening multiple views on the same outline.

The panes feature also seems to allow Workflowy to mimic the major selling point of Legend. I have been developing a fondness for Workflowy. I think it is going to become a focal application for me in retirement.

Workflowy is great, and its continuing development and large ecosystem is comforting. Have you found a way to bulk-import data from other applications? It would be a lot easier to move on from Tana if there were a way to get my information from that app into its replacement.
