This is an insightful article. Constella is alluring, no doubt. But I would also urge those who are intrigued by Constella to take a look at TheBrain, which has been around for over 25 years and is constantly being developed. It is a little more expensive, but it also is more feature rich -- but not in a bloated way. It provides an endless canvas for connecting notes. You can pack any files into notes. Notes (known in TheBrain lingo as thoughts) are accesses through an automatic hoisting, but connections are all visually available. Not saying it will be better than Constella for you or anyone else, but worth a look.
