I might also suggest folks look into TheBrain, especially if Constella apeals to them. TheBrain is more expensive, so if price is a concern, don't bother. But TheBrain, in my view, is more powerful than Constella. Like Constella it provides an unlimited graph view, though The Plex (as it is called) works differently. It works in permanent "hoist" mode, where the note (Thought in TheBrain parlance) you're looking at is hoisted to the center. All notes related via links are also visible on the screen, separated into child, parent, sibling and jump thoughts. The note taking area is far more robust than Constella's. Though not as friendly as Constella's, the AI features are pretty powerful. I'm not saying people should choose TheBrain over Constella, but if, like me, they find Constella a bit wanting, TheBrain might be a good alternative.
