Like for example on the image i linked to the question you can see two preview boxes one representing two screens. The left box shows what is on screen two 'the one on the right' and the right box shows whats on screen one 'the left one' so if i click on the left box it takes me to the firefox tabs on the right screen. How do i make it so the left box shows tabs on my left screen? and the right box for the right screen?.
