Bring back the interface of the zone-system

Is your feature request related to a problem? Please describe.

I found the old, discontinued zone system highly intuitive.
It clearly showed how you were distributing dynamic range, and how you could take some dynamic range from a portion of the spectrum and use it somewhere else.

The Filmic does that but it's like there are only two zones (dark and light) and it's not as visual.

The Tone Equalizer seems to redistribute the dynamic range but again it is not so clear exactly what it is doing. For example, increasing the (-8 ev) changes the mid-tones.
The zone-system interface was very intuitive in that respect: If you want more details in one range, you will give it up in the others.

Describe the solution you'd like
I would like the user interface of the zone system, with the 8 bands, either in Filmic or in Tone Equalizer.

This is about the user interface. I am not asking about the zone system to be returned although I would not mind it.

Alternative would be some kind of display how the dynamic range is distributed.

No file, test, or entry point is named. Start by reviewing the existing Filmic and Tone Equalizer interfaces alongside the discontinued zone-system design shown in the attached image. Define an eight-band dynamic-range display that communicates redistribution clearly without restoring the old zone system, then verify the UI against that requirement.
