This is something I've been thinking about for quite some time, but it never seemed relevant. In the content of this thread, however, it might be, so I'll mention it!
* When watching a game - either a turn in progress, or moves happening in history - sometimes we want to see a specific part of the map, to see what's happening there, but the autozoom and camera jumping around can make it really hard to see what you're trying to pay attention to.
Sure, you can go manually, order by order, but that can take really long (especially when watching the History on a large map) and still makes it harder to watch for whatever you're looking for.
I've often wished for a "static view" option, where the screen doesn't zoom or move as you watch the turn progress. (Ideally, it wouldn't even process or show other moves happening "offscreen", but that might be impractical.)
Imagine that you want to review a tournament game, because you remember that Player X used some clever tactics against Player Y, in a central bonus in the top-left portion of the map. You might want to watch the whole game, to see how they handle that particular area.
If it's a short game, a small map, and two players, that's not hard to do. But if it's a giant map and there are 10+ players, watching through the History while trying to pay attention to the action between those two, and in that region, is very time-consuming and very difficult.
So, now, imagine that you could simply "lock" the screen on that one patch of the map, and, as the History progresses, just watch what's happening there, without being distracted by the action on the rest of the map.
It would make reviewing important events in games much, much easier, and could enable some pretty great Warlight videos, too (for people who make guides, playthroughs, or review other people's games).
When the "change perspectives" feature was added to History, that helped a great deal, but sometimes it's not enough to do the trick (especially in team games).
