Highlight and shadow warnings

I have no idea if this could be an option but could/would it be possible to add highlight and shadow to the plug ins?


for exampe in Color Efex Pro it still exists, but the visibility is not so good



For which pug-in do you miss that option?
It’s also in Analog FX, HDR FX and the new Viveza 3, while in Silver FX 2 and 3 we have the zone system.
