Ideas and suggestions.

Was watching a Jebus Cross game and had an idea about spectacle. What if we changed the game viewing format to a condensed and post-factum one. Create a mod (or improve an existing one) so that it automatically takes screenshots of important events (hero leveling up, building construction in town), etc., and then stitches all of this into a video sequence.
This would cut down time spent on movement, battles, cursor-waving across the monitor, and most importantly - the opponent's turn. Of course, a ton of information about the specifics of a particular battle and such would be lost, but sacrifices have to be made somewhere.
+ I think applying this kind of digest add-on to game reports would greatly improve them.

+1! I've been thinking about this for a long time! Let me add my two cents - make it possible to screenshot the entire map at once, including a mini-map variant that shows both air and ground views. It's painful to watch streamers manually screenshotting this map piece by piece.
