I uploaded a new version of Message Notifier to extensions.gnome.org. The main new feature is that you can now open the menu pressing Win+M.
The default keybinding can be modified by clicking the preferences button on the extension page (next to the switch to enable/disable the extension).
This version also fixes notifications for xchat-gnome on Fedora.

Works fine on Fedora 17, good job!

Hey,
Just a heads up, the latest proposal for message tray redesign uses Win-M:
https://live.gnome.org/GnomeShell/Design/Guidelines/MessageTray
So there’s a keybinding clash there.

Hm, I didn’t know it. For now I will leave the default as Win+M and then see. I’m not sure if this extension will be still needed when the final design of messaging in the shell will be available.
