A little forward: Window_Name is softlink to window directory, but can't solve 'readlink .../window_name != window_id', due to required globbing and possible multiple windows with the same name.
I think I fixed that. I don't want to check it now, and I have an inkling that it is a hack.
Updated configurations: tmux send-prefix , zathurarc placeholder , and zsh: PATH addition , perl configurations
