I might re-organise the equipment slots at some later date. As I said, the entire thing barely holds together so I don't want to poke in it too much. Getting the new slot to work took me almost an entire day as is.
As for the mutations, they poke through for now, but it doesn't look that bad (or good). I will wait for some feedback once the version is out and I might just make them invisible if you are wearing a helmet. We will see.
