It took some time but actually i got a response from the Steinbergsupport
There is no further development planned regarding these features.
- The CMC are not capable of doing such feature. ( Answer to handling Inserts / plug-in control like the Nuage)
- They already have a feature assigned when you have a muted or soloed channel they blink… that is why you can not assign that option to the selected channel. (Answer to why there can’t be a better visual feedback on the selected channel)
