Would be nice that when after you get a skill, there's an indication what level you get the skill, so if you want your other character to get the skill, you'll know what level your character has to be in order for it to get it.
You can also buy an emporium badge once you get there, the star shaped thing. Then you don't have to wait until you get the purple scroll to get to the shop.
