When watching replays, have the option to show these details for all players at the same time: Mouse cursors Viewport outlines on the map, all of them Click+drag bandboxes Unit selection boxes Also allow watching of these particular things for one specific player at a time: All of their viewports Order queues when pressing Shift Order queues for specific units when selected Basically show as much of all players' perspectives at the same time as is possible, and when you simulate being one of the players, show everything they were looking at while they were playing. It would also be handy to be able to see your teammate's mouse cursors, viewport outlines and bandbox and unit selections during actual gameplay. If the game has a scalable UI, then everything they see should be possible to scale down to any resolution even if it's not the same aspect ratio. Just block out the non-conformant parts of the screen. If you guys don't have time to implement this, it would be great to have access to these features from a mod, or to at least make the architectural considerations so it's not too hard to implement later.
