Hi @sjiep
It started back here:
I3wm for EOS net-install - lets do it together! - Desktop Environments / All WMs - EndeavourOS
It is very much a community effort in conjunction with @joekamprad. Some of the bindings are joe’s others came later from the community. So in the end EndeavourOS i3 is very much a “custom” spin on i3.
It is also designed to make the transition of new users to a tiling WM easier.
