I do think that the idea behind the glass insert is for visability...it's the only thing I can imagine. The metal where the glass inserts into the foot is where the feed dogs are, so it's not as if the glass has any other purpose that I can see...I'll have to get ahold of Miller and see if he knows for sure!
