Sensory changes. Touch, taste, scent, and visual -- I've had all of them expand and change.
I respond to touch a lot differently, with a number of things that used to be irritating suddenly quite pleasant.
Visually, I seem to have a better eye for color -- picking out shades and differences I couldn't before. My spouse has noted it a few times.
My sense of smell has increased, and I've become MUCH more sensitive to certain smells -- for good and ill.
Taste has been weird -- I'm definitely capable of tasting more complexity than before. I've not encountered any 'favorite foods' that went from good to bad, but I've found SEVERAL foods that went from "bad" to "good" (bananas, for one) and others that went from "meh" to "good" -- coffee, for instance.
I don't know about hearing, but I know those four all got more...nuanced.
