- Opening an email thread opens multiple (potentially many) tabs, and is difficult to nagivate or understand the flow of messages
  - I don't know how to write an email without it making the spacing between paragraphs/lines larger than I would like. (I.e. double-spacing)
  - Search is unreliable / broken.

Just note that XDG_DESKTOP_DIR and XDG_DOWNLOAD_DIR can not point to the same directory or chromium will disregard your config.

P.S. Reader, if you can commit to chromium without much hassle, check this and fix: https://wiki.archlinux.org/title/Talk:XDG_user_directories
