An XML Data Editor

I have developed an XML data Editor, It would be nice if some people who use XML could give me some feedback (preferably constructive on how to improve it)

It is designed as an XML Data Editor, I make no effort to edit html or any other standard xml file, only data for ecommerce and filing.
 
it is available for down load from here http://www.users.bigpond.net.au/tcroll/software/xmlnotetree/XMLNoteTreeHelp.htm
