Speed up the lecture of the timeframe

I'm using Screenflow mainly and when I switch to screen studio, i'm really missing the feature of speeding the timeframe to be more productive on post-prod.

On screenflow, I just need to press "L" letter to x2 on the timeframe speed (only for post-prod), that's not affect the video speed.

Their killer feature is when you press multiple time on letter "L", that speed up again, like : 1x by default, press L to x2, press L again to be on x3, ...

I suggest to add it in Screen Studio :)
