Yes please! Track keyframes are incredibly useful, particularly for me when using submixes. The inability for these keyframes to ripple is a major limitation.

Totally agree with this and need this feature desperately. We show rough cuts and edits to producer in theater environments with 5.1 mixed right in the program. All that work is useless once you make a single edit.
If this feature is difficult to add then add the ability to pan 5.1 on the clip level like Avid.
Bypass the full track concept until you can figure it out.

Agree.

I use aux channels a lot to mix different parts of the audio (dialog, music, etc). This is a case where I very much would like to be able to easily move track keyframes along with clips when making edits.

Working this way allows me to change the music track and maintain any ducking/swells I set up, but having to move keyframes as a separate step is a major downside.

100% this.
I'm working with a soft locked cut, and I would love the ability to have an option to ripple the audio track keyframes when small tweaks are made to the segment durations of my show.

Jim Simon. Not exactly.

If I have a music track with lots of edits, track fades may occur over clip edits. THAT's why I used track edits. If I then need to ripple a program after I've done my track mix, having the OPTION to turn on a "Ripple track keyframes" function would be very handy.

I understand what you are saying, but I like the concept of having that option.

What you want defeats the purpose of Track Keyframes, which are independent of underlying media. If you want Keyframes tied to media, you need to use Clip Keyframes.
