I'm writing one. Inspiration from http://www.treepad.com/ http://www.treepad.com/ I use Treepad for notes heavily. Now I want to be able to manipulate the tree programmatically. Also it will serve for a html/js workshop for kids. They have a hard time setting up and working with regular editors and the file system. The program is general purpose (different kind of node can be handled with plugged-in "drivers"). If you're interested, drop me a mail.
