Now that I have gotten to honestly try using the shop in game, I have to say I really like it so far. I was able to find what I was looking for a lot more efficiently than before, although I did keep trying to purchase the red elixer when I wanted pots just because I had the damage page open and I see a red potion right at the top of the list. UI also did not bother me at all, although I did scale it down a bit right away.
