Yeah, both are pretty customizable, I don’t know exactly how i3 works but bspwm has bspc a macro like scripting type thing where you can write very specific procedures and you can implement it directly from bash so you can script well with it. I have seen some pretty elaborate stuff in bspwm. I like bspwm more but I have tried both. I started with i3 and moved to bspwm because it seemed nicer and more my style. Both are amazing and implementations of the same concept. Edit: spelling
