Raid replay pause/play

Hi would it be possible to make the play/pause work on spacebar. Way easier to stop the replay when you have windows taskbar hidden, and something like a whisper causes it to popup and block the play/pause button.

On that note it would always be useful to have a rewind function, or just skip back 5s. At the moment i end up clicking back 5s, and if you click wrong it jumps back to the start of the replay.
