I have removed archinstall from next release. Archinstall does require a working network connection so given you have a way of connecting to web you can simply install it. It also removes the need to ship iso with Python doe just that package. Key bind menu should also be part of next release, it is present in Conky or simply hit Super + b.
Am quite happy with how iso turned out and can now tweak it to give it a more polished feel. May add more comments to i3 config file to make it easier for users.
Finally the sun is out here in the UK so am going to make the most of the good weather.
As always stay safe 😉
