A storefront suggestion, sorting on item tier
In the second part of the store that isn't recommended items, there is a lot of ways to sort the store on the side.
One thing I would like to add is sorting on item tiers.
For example:
Tier 1 items (component items):

Tier 2 items(fused items):

Tier 3 items(completed items):

This way you could find items quicker if you wanted to look for them in that part of the store.
