PLS Center Vertical Layout preview Window -

Can we change the preview window back to being in the middle of the layout, or at least have the option for it?

I understand trying to give as much real estate as possible to vertical videos, but in pretty much any program I've used, be it video, 3D, Photo editing, Illustration, what you look at is in the center, and the peripheries are for menus.

It feels very unnatural to have the preview off to the very edge of the screen.
I also found having black around the preview when it was in the center, was helpful for doing color.

If it were centered, it couldn't fill the vertical resolution of the display. (Else it would cut the timeline in half.)

Can we change the preview window back to being in the middle of the layout, or at least have the option for it?

Yes, you can disable "Use optimized UI layouts for vertical video". The vertical video viewers and layout will revert to standard.
