As beta's go, this is pretty awesome despite a few rough edges here and there: 1) IE 11 scaling in desktop is all weird when moving the browser from your SP to an external monitor. 2) They still don't have the independent zooming for external monitors working properly for Modern UI and Desktop apps. 3) Although I like the new Favorites Management in IE 11 Modern UI, I wish the Favorites List would persist instead of having to hit the star button again each time. The default is to show your tabs. I wish I could set the default to Favorites. 4) The squares they use to represent favorites seem like a waste of space to me. Wouldn't lists or a folder tree be more efficient? Also would be nice to be able to dock favorites to a sidebar as in the Desktop version. What do these squares do for me? If they were live tiles that would be kind of cool I suppose, but as it they are just big 90% empty squares.
