Great idea akafox. The support for Mala layouts is probably lacking in a couple ways, since I really just cooked it up after playing around with a couple of layouts that I wanted myself as well as the Mala layout editor.
So feedback about what works and what doesn't would be helpful. If you want to hack around with how mala layouts get loaded yourself it is actually fairly simple to do... mala layouts get loaded by the attract-mode layout .nut file located at: loader/mala.nut so you don't actually have to change anything in the frontend itself.
