In what area is Pro Tools REALLY lacking??

[LDS]

Currently 2018.12 and 10.13.6 are running pretty damn nicely on my system with HDX. I did a clean install, and made a very concise list of what plugins I need... rather than my usual habit of just going to town and installing everything I could get my hands on. 95% of the free plugins I have collected I never actually use.

What I would love to see is:
- MPE support added.
- Better I/O control, with the ability to have analogue inserts use different output channels from input channels and sample based I/O delay offset instead of millisecond based.
- A simple option to reconfirm all surround channels to the desired standard (SMPTE, Film, etc).
- Dedicated surround channel mixer plugin. Something along the lines of the sound field plugin that gives you the power to change channel levels and locations of a surround channel.

I'm sure there are more...
