Simultaneous Master Chain and Playback plugin visibility

To my knowledge we’re not currently able to open more than one plugin at a time in the Editor (single) mode, which is incidentally where I do most mastering work. Would it be possible in the near future to allow a Playback plugin to be visible simultaneously while a Master Chain plugin chain is opened?

I’ve seen a similar request before in 2014, I believe, but my use would be that I could see the effects of a plugin with a metering plugin by seeing both open at the same time.

More, I’m wondering if, in the future it might be possible to embed a plugin into a save Workspace layout.

Thanks!
