I absolutely despise the following directories: Documents, Music, Pictures, Public, Templates, Videos. Why? Because applications randomly dump stuff into these directories and fill them with junk files. I don’t want any application putting anything into directories I actually use, unless I explicitly tell them to. It is not possible to keep your files organized if applications randomly dump trash files into them.

If you care, please take time to upvote or file bugs on packages that don’t follow XDG. Or even better, make PRs.
