Most of Solomon's wares are one-time purchases. After making a number of purchases I now see page after page of items marked "Purchased". It would be nice if we could have an optional filter that hides these items so we can actually browse the store for new purchases instead of spamming "next" until we find a page with an item marked "Buy".
Also, with the filter active, the counts on the left hand side should decrease to show the number of items we can still actually buy in that category.
