1. something simpler and more declarative than bsmedberg's DLLLoader (btw, it does not work with xulrunner-based applications ; confirmed by Paul Rouget)
  2. something in the toolkit to minimize an app to windows systray and specify (a) the action when the icon is clicked (b) the contents of the associated context menu
  3. I still need an event notifying me when a given window is moved by the user on the desktop.
  4. an official (ie available on ftp.mozilla.org) "developer edition" of xulrunner with venkman and inspector so a xulrunner-based app author only has to call window.openDialog() to launch them.
