While watching a replay, you often want to skip bits. Often because you aren't sure where exactly the moments you are looking for are. When you finally reach that moment, or perhaps when you anticipate a battle, it is very tedious having to press ----- to slow it all the way down.

I believe that pressing 0 in replay should put it on regular speed (x1), so that people can easily skim through them without having to rewind back. Simple but nice change.
