Improving replay in future updates of CS?

[PawelM]

I play a lot of large scenarios (team games and 1v1). I also watch the replays. What I find frustrating is that the replay of invisible moves of my opponents (with FOW) are replayed in the background as well. So, I end up "watching" a lot of static screen. Tonight, my frustration with such replays was high after watching 20mins replay (this is already with animation speed set to maximum thanks to the latest patches-although I am not sure if it makes a difference with invisible moves in 2D view which are not animated anyway?), with not a single move being actually in LOS. So, 20mins to watch a static map followed by end of replay message..A bit disappointing...

I wondered (a purely speculative question to dev team), what is the scope of reducing replays to only visible bits? Is it possible, possible but difficult or completely impossible?
