It would be very cool to be able to view/watch a log file ingame.
Mockup image :
A new button named "View this log file ingame" could open the game window and "play" the log file just like if we watched a game as a spectator.
Also during this "show" it would still be possible to speed up the game with the slider !
It would be another method to view log files, but in a more realistic way.
