Comment 138 for bug 44082

one of the comments suggested escalading the issue to Canonical, you are free to take a support contract and do that if you want, otherwise there is no formal way to escalade the bug since Canonical employees are pretty much free to decide on what issues they consider important enough to work on. The bug described here might annoy some users but don't conclude that it's an issue for everybody, I'm using GNOME since before Ubuntu and I get some applets position changed maybe once a month, it's a bit annoying but it takes a few seconds to fix and I don't consider that as a showstopper bug, ie I'm not going to spend days on the gnome-panel code to try to fix that bug but other people are free to do the work if they really think it's important to get done for Ubuntu
