Not a big deal obviously right now, bit i would like to e able to save my replays if that would be possible at all, I just like going back and watching old games or looking how i could have improved in previous games. Also I think it could be cool if the replay allowed you to actually see what your enemy is doing. Except for when you enemy is in your view. Again if this is at all possible. Just to see how he reacts to you so you can try to predict your opponents movements in the future.
Technically "ChronoCam" it's both replay/save/spectator system, so when Uber implement that feature you'll able to use replay as save game that let you load from any point in timeline.
Saved replays is coming. Also, in the replays already, you can toggle to yours/your opponents point of view. just click the little box next to their name. Is that what you meant?
Technically, it's anyway broken currently (when rolling backward, many destroyed units keep displayed as destroyed while then should not be). So until this is fixed, saving replays is not very usefull.
Actually ChronoCan fully functional for me, but it's eats about 7mbps of bandwidth and sometimes I need wait a while before it's clean up map from old projectiles and structures/wrecks.
