This little script in my i3 keybindings opens a new terminal with the same working directory as the currently focused terminal, pretty useful for my workflow:
bindsym ctrl+$alt+t exec xdotool getactivewindow getwindowpid | xargs ps | grep "alacritty" && (xdotool getactivewindow getwindowpid | xargs pgrep -P | xargs pwdx | cut -d":" -f 2 | xargs alacritty --working-directory ) || WINIT_X11_SCALE_FACTOR=1 alacritty
I probably scratched some parts together from the internet a couple of years ago.
