The title virtually explains it all. It's not completely necessary, but it gives the whole information feel to the pages and can be really helpful.
Also, when we click on an item on the item list, could we make it so that on the page it shows what Pokemon are holding that item in the wild?
If you need help (or are too busy to) find the information on items rates etc: we could easily find it for you, if that is what you would like.
