I spent a few minutes with the online mind mapping tool Mindomo.

Here’s what I’ve found so far:

• Saving takes time – and it doesn’t seem to happen automagically …
• No export to FreeMind format 😦 – I used Mindjet MindManager format as the intermediary
• Has a notes capability – “F12” is the hot key
• Expand/collapse feature is present – nice!
• Links don’t seem to be active …
