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.

It would be nice to have instead of scrolling down, but I doesn't serve any use unless your a marketeer. Plus, what practical use would it have for anybody who is a marketeer?

I usually check people's account history before I offer on something. That makes me decide if I should offer higher or lower. Sometimes I lost in there. Checking 10-20 pages trough. This would make things easier for me, also I'm not the only one. For scam reports etc, It can be useful for staff too.
