I think grouping items would be really nice for navigation. I think this is much needed since there isn't any way to sort transactions. For example, I have 446 pages, and I can never find anything. If you're buying or selling from a lot of a single item shops, it'll easily fill up your rupee history. Same thing if someone else is buying or selling to you. This especially happens when things are sold in small quantities in shops, and you need to buy a lot of it.
