Just bear in mind that VS control the electronic windows at night time. If you want to 'open' the window to look at the dawn coming up? No chance. Then, the use a 'wake up design' and the window changes colour! For this reason alone, I have foresworn riding a VS 787 again - unless there was a family crisis.
If a 787 is in the offing from another carrier - I shall try to find out their window policy. I like to look at the world, day or night, and VS 787 do not allow this.
