Move every file from plugins into zshrc.d as well as all bigger blobs in the zshrc into their own files there. Some stuff is still in there that I am not all too sure where it belongs. TODO: Move. Because all external plugins are now sourced over a symlink I had to create a fork of fzf-tab for now that supports that. See: https://github.com/Aloxaf/fzf-tab/pull/153
