Side by Side panels

I’m not sure if this is possible already, but do wonder if one can have the Inspector and Style Editor panels open, side by side at the same time. I do most of my UX development work directly on FF, and spend half my time switching between panels. It would be just amazing not to have to do that. Any hints would be greatly appreciated.
Thank you.

I personally proposed a a feature that could suit to your needs. I hope that someone could consider it
