I've just created a new product called "Oxygen" in bugs.kde.org.
It has 4 components: style, window decoration, icons and sound. So please use these in the future if you know the bug belongs there. I'll be adding known bugs from our wiki in the coming days
I'll use this opportunity to also ramble a bit about bug reports. Because though in general we love reports and wishes there is one kind that isn't very useful, and that is the category I'd call "I don't like the look of.."
