I made this because it was "possible".
THIS IS NOT INCREDIBLY HACKY!!! I DON'T RECOMMEND DAILY DRIVING THIS!!!
But if you still want to try it out, here's how
# Running this again will close it
eww -c ./ open-many windowbars bar --toggle
# Remove borders
swaymsg default_border pixel 0
# citsfsip manages tiling. This is optional because you could still use sway tiling
swaymsg for_window '[app_id=.*]' floating enable
./scripts/citsfsip.py
Note that this config gimmick was made for a single 1920x1080 monitor.
If you encounter any issues, fix it yourself.
