I think it would be very helpful if there was a way to view one's own transaction history, where players can view anything they have purchased within the past [enter time span here, ex. 24 hours] be it with gold or platinum.
I'm currently finding myself in a predicament that I feel could be solved by this suggestion: Yesterday, I had well over 100k. I now currently have only 25k and I have no idea where that gold went. Not sure if I was hacked or not. I have already e-mailed support and am waiting for the issue to be resolved. Albeit, I feel like incorporating the above suggestion could have been a huge help. I'm sure I haven't been the first person with this sort of issue, and I'm sure I won't be the last.
