Allow opening a new window without pinned or essential tabs

[KarimAlaswad]

When opening a new window, I want to have an empty window and the tabs I want in that window, but I don't want my pinned tabs or essentials there.

I like that.
That, and when dragging a tab out of window to create another, a window without pinned and essential tabs would be nice. Loading all the tabs in a new window takes some time.

I think Arc calls it Tiny Arc or Blank Window

I agree that would be a super useful feature especially for multiscreen users, like myself.

Some of my essential tabs are very heavyweight in RAM consumption (eg slack, gmail). Having them in a second window makes it easy to accidentally click them out of habit and then load a second copy doubling the ram consumption. Either it should be possible for the second window to not have them or (far cooler) to let all windows "share" a single instance of each essential and/or pinned tab and implicitly move it between windows when clicked on. Even if the tab could only be shown in one window at a time, that still seems ideal. It could just switch to a different (possibly blank) tab on the donor window.
