For several years now, I have looked for a mind map / brainstorm app that has the following criteria: - Infinite drawing area. Ie no restrictions on size of the map. - "Zoom" / "Focus" function; When clicking on an object that object should be highlighted, it's neighbour (sibling) objects should be somewhat dimmer, and their neighbours should be even dimmer. Any suggestions? Or do I have to learn to program to get what I want...?
