Comment 6 for bug 1051856

It has been decided after several discussions (some time back) that notifications would not provide any actionable buttons such as close, open etc. The reasoning for this can be found in the ubuntu wiki for notify-osd. You might have to take this up in the ayatana mailing list if you disagree.

I am closing this bug as it is not relevant to Unity. Since the problem exists within a thunderbird plugin, you might want to get in touch with the addon developer.
