1) Items/Furniture: When on the select info page of an item, such as a cherry, or a type of furniture, or type of furniture with a specific link, there would would be a link on somewhere on the page that would direct you the the auctions of the specific item. The advantage goes mostly to someone who's buying furniture, because you don't need to decide on what cherry to buy.
(You could list the vendor, but those will go away someday.)
Why this could be a bad idea: Auctions could be wiped clean easily if people had easy access? Maybe it would take the same rate.
The other ideas will pertain to item menus, what links are missing, and what not [more to come].
Here's a draft:
The Crystalmalizing (spelling) Chamber:
-It's an expensive tool that should have it's own menu, that only appears as an option, should you not have enough barnacle talc / Firefly jars. Why? Because then you could go on the menu, and it would list the ingredients like a kitchen tool, and then there would be a make more option for barnacle talc, if you had enough un-crushed barnacles. Then menu would switch to the grinder, and then you'd simply hit the chamber and then make a crystal.
(Not that we can search through our bags easily, this does seems like a unnecessary idea. And the fact that you can only make one crystal at a time. But this is just an example)
