Well, I don't know if this function already exists, but I think it would be really nice to add it, which would be some markers in the recording, for example, I'm playing a very long game and something funny happens, so I just press a button (whichever one I choose) and when you go to see the recording it will be marked in the recording.
Thanks for the feedback, this option is already exist. You can place a bookmark while recording, see the hotkey for it in the game's settings.
