I've just upgraded to Object Dock 2 and it's looking pretty good and solid. However I think the mechanism for deciding what system tray icons are shown is the wrong way round. I would prefer that one chooses icons to hide, not show, so that any previously unseen notification icons or new apps get shown. As it stands now, I can easily miss icons because they don't appear unless I've gone in and checked what's not being shown which is not the point of notifications.
Apart from that, well done guys.
