Yup, that is what i a have so far as well,
but it can be opened from a Convo directly without the need of Contaclt list, being open
i need to open it without any oter window open from the tray
it is so much simpler
Window Manager is discontinued, for WLM try the new, Enhancer for contact list docking, auto-hide, hide taskbar button, remove button flashing and remember keyboard layout in conversation windows
