Microsoft Edge. Bring back the option to fade inactive apps.

I'd also like this fading tabs feature restored. I just updated to the latest version of Edge and was appalled that this essential feature is removed.

Like others have mentioned, fading tabs help in my workflow in the following ways:
1. Clear visual indication for the psychological reassurance that sleeping tabs are indeed sleeping and not hogging up resources (which is very important when you have 100+ tabs open). edge://discard does not even work reliably when you have a large number of tabs open.
2. It allows me to see which tabs I have interacted with recently (within minutes or so), letting me follow my train of thought during each research session more clearly while ignoring the clutter/noise of other currently unrelated tabs (reserved for another research session), as I have sleeping tabs set to 30 seconds (also as n3n5n1 pointed out, wish this is customisable so I can set an even lower value). I suppose this is even more apparent while using vertical tabs, which I believe most people like me who have many tabs open at any given time have already adopted as the standard.
3. Brighter colours are not easy on the eyes - again, adding to the visual clutter and lost productivity.

Please revert this change. It was fine before as an option where users have a choice, even if it was opt-in. What was the reason for removing this choice at all?
