I have a more unusual reason for wanting a right-side tabs bar. (Not the same Right-handed reason, as I don’t have a touch-screen, so right handed isn’t an issue)
Basically, My computer is set up as a direct “mirror” of my wife’s computer. As in, My secondary screen is on the Left. (While her secondary screen is on the Right)
So on my computer, if I want to mouse over to the Second screen, i currently have to hop over the tabs bar.
So basically, moving the tabs bar over to the right of screen would be better for my PC setup.
