On the main "Preview/Program" page, currently the main audio is displayed with a VU meter that doesn't have any dB level markers. As a result, when producing a show, you are left essentially guessing where your main audio level is peaking. However, you can go into each individual input to see the audio settings with a VU meter with dB markers. So, I'm confused why there isn't a main audio VU with dB markers (screen real estate??). Request: Could you please add a VU meter with dB level markers on the main page.
