"Weighing in, I think that Canonical's work here is looking really good, and has a wonderful design, but I do worry about some of the edge cases. The biggest other concern is that no effort until recently was put into contacting Christian Hammond at all, so it's essentially a fork/reimplementation, even if it is one that makes sense due to upstream's stagnation (until recent developments). Now that Libnotify and Notification-Daemon are up for proposal for GNOME 2.26, it's only now that we’re looking into replacing it...It’s both unfortunate and opportunistic of Canonical to pull this out of their hat at UDS.
"For those that are not here at UDS Jaunty at Google, it is important to understand some of the changes that we have discussed here. The first of which is the removal of "Actions" from notifications. This means that there will be no more buttons inside the notifications at all. The way that applications currently use libnotify is somewhat abusive to the original spec, where they should query for capabilities and then use an action if the daemon supports it, but changing the daemon now to simply never show actions will likely leave you with notifications that say "Please click the button below", and there is no button to press. Bugs to be filed, users to scream at us..."
