A few days ago, Gorillized announced a utility to import Circus Ponies notes into their Outline. When you join the “waitlist” for this utility, you are offered the opportunity to inform the developer about the Notebook features that are most important to you1 and you will be notified when the import utility appears. They also offer a 30% discount off the usual price ($40) for Outline for Mac. The iPad version costs $10. Both versions support Dropbox, iCloud Drive, OneDrive, and Box. I have no experience with Outline,2 but I will surely try the free trial (14 days) when the time comes.
