Short answer: nope.
Why on earth do you want to play the timeline while doing something else. You get cross-eyed…… 😉

I know exactly what you mean. I sometimes get all mixed up. It’s because we are trying to keep up with everything. So many apps so many different versions.

Make sure you have the latest update and the matching sequence for your footage.

Try uncompressed. Don’t export but use the queue.

RAID 0 is the fastest, but you need backup just in case.
I’ve been using raid 0 for many years and never lost data yet.

For moving along the same video track it is not needed to hold shift, only when you want to change videotracks and v.v. for audio.

Drag by position the mouse over the video part the clip to the new position in the timeline in this case V1. Dont let go of the mouse and press and hold shift. Still dont let go of the mouse and drag the audio part to track A2.
If you want the audio to stay in the same place and move the video move the clip by positioning the mouse over the audio part, select and hold shift and drag the video up.

Under General: Default Scale to fit frame size.
