Is it possible to show notifications displayed in right top (like these about being connected to a wifi), that can be clicked? Right now I can either create a notification, that can't be clicked or create an ugly notification (a dialog box), that can. I would like to have something non-obtrusive, that can be clicked and perform some action then.
Here are some Guidelines for developing Notifications
Ubuntu Wiki
I don't think that's possible, as Notify-OSD doesn't support actions.
This would be an ideal candidate for morphing windows. Unfortunately they are not implemented yet.
