Could the "files-bzr" package (https://aur.archlinux.org/packages/files-bzr/) be renamed to "pantheon-files-bzr" as this is to generic and there are other "pantheon-" packages?
Also, the "cinnamon-dev" package (https://aur.archlinux.org/packages/cinnamon-dev/) is not needed anymore, because i've created it as a temporary solution..
