Thank you for your hints. I completed the new version of the plugin. Now 
  if the node contents are changed in the outline the temporary file is 
discarded, recreated and opened in VIM.

Here I have pasted the output of the "Write @file nodes" command. Hope 
this format is suitable for you.

\bye, Andrea

#  To use this plugin do the following:
#
# - Start VIM as server: vim --servername "VIM"
#   The name of the server *must* be "VIM".
#
# - Single-click on a node's icon to open that node in VIM.
#
# - Leo will update the node in the outline when you save the file in VIM.
