Comment 1 for bug 351986

Hi Rodney, as far as I can see you pointed out many "glitches" of the new notification system.
Many of these are already being discussed in the relevant bug reports:
bug #345363: "Next track" notification appears even if nothing listening
bug #345296: confirmation bubble is overlapped by notification bubbles
bug #354149: Synchronous notification bubble does not appear under existing bubble
bug #354339: Notification bubble can change size while Confirmation bubble is visible
Some of the problems you listed do not have a bug report filed against the correct package or project.
I suggest you to comment and subscribe to the bugs listed above, and to report new bugs for the problems you did encounter with the new notify-OSD: a bug report should list only a problem, without going off-topic.
