search transaction history
I think it would be nice to be able to search for items/people in my account history, similar to how you can search in your inventory. A simple search bar(s) for typing names of people/items that yields a short list of the past transactions would really come in handy sometimes. For example, if I wanted to find out if I had previously done a trade with [example], then I could easily do that. I can't see any reason why this would be a bad idea.
