The current way of finding the PID of the active window is quite fragile due to the extremely loose regex in place. Since xdotool is already a dependency of multiple other scripts I'd recommend just using that.
* Programs that show ~/ or / instead of the actual working directory are now ignored by the script (except for zsh & lf where its correct). This will fix bugs where sd opens your home folder instead of the current working directory.
* This also removes the need for manually excluding all programs that don't show the correct cwd.
* git (and its sub-processes) will show the root of a repository instead of the actual cwd, so they're ignored too.
