I think this is a feature request rather than a bug but I was hoping that when selecting -colors-4bit it would still produce a palette where there are more than 16 unique colours by creating the necessary entries in offset banks and setting the map attribute appropriately. I thought that -pal-full would do this but maybe I misunderstand what this parameter is supposed to do as it doesn't produce the correct colours. Thanks for what you've done so far though, this is a great tool.
