Pretty self explanatory, but it would be awesome to have a built-in replay buffer for the rock cam. I don't usually like recording entire sessions and combing through the recording for clips I want to keep, and a replay buffer makes finding clips from play sessions much easier, since the moment I clipped is usually quick to find.
I can already use a replay buffer using OBS, but that requires going to my mouse or using an overlay to hit a generally small button or binding a hotkey to it with very little in-HMD feedback. The rock cam is physical, has very good interaction feedback and telegraphs to another player that you're doing something more obviously.
As a side note to this, it would be nice if the rock cam's settings persisted across scene loads so that you don't need to reset the smoothing/FOV + view modes between matches, which would be especially pertinent when using the cam to clip fights in case you forget to reset settings. I could probably mod a basic playerprefs implementation in though.
