I miss Google Notebook!
It would be nice to have a "Past from browser" feature that :
1) creates a new node with current browser page title
2) adds current browser address as Hyperlink to the new node
3) adds selected browser page text (and images would be nice) as content to the new node
I think this feature would capture a lot of Google Notebook ex-users.
Alternatively a browser plug-in to do the same would be nice also. It could use a configured Freemind file and default node or current opened instance.
