I'm greatly in favor of more readily available information on game events and stats. Three of the greatest weaknesses of the game is the scattering of information, the amount of repetitive tasks, and the needless amount of clicks to accomplish anything. More information in one place will alleviate all of these problems, allowing players to spend their effort on strategy instead. I suspect one of the reasons for these seemingly clumsy solutions has been the need to keep players busy, back when there was less "real" content. Today, I think that need is adequately met by better content. They should consider making a concerted effort at improving this, even beyond incremental and ad hoc solutions like this. In the absence of a more comprehensive solution, though, I'm very much in favor of this one.
Event History can help quite a bit, but still leaves you to process and collate the data outside of game functionality to get a deeper picture of events. Since copy/paste doesn't work, this is a tedious process, to say the least. Sites like foestats.com help, but still leaves great gaps.
By the way: To get filters for Event History, click the little blue button at the top left corner of the EH window.
