The best app ever for organizing!!!!!

This app is amazing for categorizing and organizing different things, I'm using it for med school and it has been awesome. The ability to import pics, record, and put in hyperlinks is amazing! I've tried mindjet, mindmeister, and they either lacked in fluidity and/or customization this app has both. The only improvement that I would love to see is to be able to save pics when inside the built in web browser. In the current version you can only make a link but can't save pics or import them directly from the browser. Other than that, perfect app.

Good app

I've been looking at a number of mind mapping apps and this is the first to do a good job of cross linking. When you select a node a temporary menu shows up displaying all the links. Selecting a link will take you to that node. Even better, if the selected node is out of site, it moves you to the linked node! This is great as it makes browsing a complex map much easier.

Things I'd like to see (and make it to 5 stars):
Larger map
Choice to not have an icon
Ability to add more icons
Better pinch and expand to zoom in more
A browse mode that auto centers when you select a node or jump to a linked node.
