This is a nitpick. It doesn't actually bother me or anything, but I figured since I notice it everytime, I would bring it up.
When you add an item to your collection the first checkbox is cart/disk/item.
Disk is (generally) the term for magnetic media such as 3 1/4" floppy while Disc is optical media such as CDs, DVDs and Blu-Ray. I was wondering if given the prevalence of Optical vs Magnetic media, this should be reflected on the checkbox.
Like I said, it's a nitpick. Just figured I would bring it up.
