Audio waveform not accurate

When trying to cut screen recording, audio waveform has offset compared to audio that actually being played back, which makes cutting out silence SO inconvenient because you have scrub to figure out actual cut point.

Some editing workflow feedback:

1. an option to disable auto-playback when moving mouse on the timeline would be nice to have.

2. ability to add multiple sensor masks at once

3. animate zoom area during automatic zoom in

4. Ability to alt-drag element to copy it on the timeline

5. insert screen recording into the same project.

Thank you
