These are a few additional features that are value-adds in a mind mapping solution:
Organic mind maps: The flexibility to draw anywhere and sketch anything (like on a whiteboard) is key to making sure a brainstorming session maintains a creative and adaptable approach to project planning.
Collaboration feature set: Collaboration should be as easy as commenting, @-tagging, sharing, and uploading. Bonus points for tools that go above and beyond here, with features like collaborative note-taking.
Mind map template library: An easy way to get up and moving quickly when you don’t have time to start from scratch. Templates should cover different types of maps, like concept maps, org charts, flowcharts, UML diagrams, etc.
Keyboard shortcuts: Built-in quality of life tools should be available for users to quickly perform basic actions like adding comments, shapes, notes, and attachments. The less time menu-ing, the better.
