My favorite feature of Workflowy is that it sends me a daily summary of what's changed in my Workflowy, i.e. sends me all new and changed lines in an email.
I would love to see Dynalist support this.
The reason I love this feature is that I use Workflowy (1) to figure out what tasks I need to get done, and (2) to let my assistant know what those tasks are. Every day, Workflowy automatically emails me any lines I add or change, which Gmail automatically forwards to my assistant. That way, my assistant is always apprised of any new tasks I've added list.
