I think they should sub categories to housing items in the Bazaar, that way it'll be easier to find and buy the item you want.
For example if you want to buy a Statue, just hover over the Decoration icon then click on 'Statues'. Or maybe you want to find a Music Scroll from a specific world, then you hover over the Music Scroll icon and let's say you want music from Azteca, then you click on Azteca Music Scrolls.
I personally think this would be a great way to buy items. This also would apply for Pirate101.
Thank you if you guys take this for consideration :)
