But it is. In the XDG user dir spec.
cat ~/.config/user-dirs.dirs
XDG_DESKTOP_DIR="$HOME/.Desktop"
XDG_DOWNLOAD_DIR="$HOME/tmp"
XDG_TEMPLATES_DIR="$HOME/tmp"
XDG_PUBLICSHARE_DIR="$HOME/tmp"
XDG_DOCUMENTS_DIR="$HOME/tmp"
XDG_MUSIC_DIR="$HOME/tmp"
XDG_PICTURES_DIR="$HOME/tmp"
XDG_VIDEOS_DIR="$HOME/tmp"
Note that XDG_DESKTOP_DIR and XDG_DOWNLOAD_DIR have to point to different directories. In hindsight, this is obvious, but this is also a really stupid "security" bug-o-feature that costed countless hours to countless people.It's not obvious at all. The only security issue is programs dumping "downloads" on your harddrive without asking you first. Sucks that this is yet another thing that Mozilla has copied from Chrome without thinking.
