m3 Quick Summary

• It's a mind mapping program that reads and writes Freemind and Freeplane .mm files
• Try it here: glenreesor.ca/m3
• You can use it as a mindmap viewer on your own website. Here's a simple example

Some More Details

• It works in Chrome, Firefox and Safari on Windows, OSX, Linux, Android, and iOS
• If you're using Chrome, you can add an icon to your home screen, and it will look and behave like a "real" app on your device.
• Provide feedback, get help, or look for announcements at the m3-users discussion forum.

Important Things to Know

• m3 stores your mind maps in your browser's offline storage. If you delete that, your maps will be gone. So don't do that 🙂
• If you have already used m3, it doesn't update to the next version until you load the page twice, due to a quirk of a technology called app cache

Change Log

2017-07-20 - Version 0.12.0
    New Features
        - Significant performance improvements for loading, scrolling, and folding
          large maps, especially on iOS
        - Switched from dotted links to open arrow heads when one end is hidden,
          due to terrible iOS scrolling performance with dotted curves
        - Support embedding m3 in another webpage
        - Added a new Welcome map that gets displayed on first load of m3
        - Center maps on initial load
        - Put popups at the top of the screen rather than bottom, since Chrome
          fullpage mode on some devices doesn't scroll contents up when displaying
          keyboard
