I'd like to make a suggest that would improve navigation and the use of your for people who are colorblind, like me.
Features that cycle between a dark red and black (such as the wishlist button indicator) are virtually indistinguishable, currently. Using a black outlined and white-filled heart to represent "not on wishlist", then using a full red heart to represent "on wishlist" would make it much easier to identify which is which.
You already use very different colors (red and blue) to identify "Add to Cart" vs "Notify Me", and that's very helpful.
Thanks for your consideration,
