When I was testing/looking about the tabs in Modern I.E. were in a drop down panel, little preview icons (more like the Chrome recently opened pages page) instead of actual tabs so they would be finger friendly and not get in the way quickly as one opened more "tabs."* If I run IE from the Start screen, and I then right-click on a link and choose Open in new tab, it appears to work, but I can't find the new tab anywhere. It looks like the new tab functionality has been removed. Therefore I always run IE from the Desktop.
