Best browser UI Expected features/improvements : 1/ bookmarks: subfolders  synchronization. Opera speed dial could be a source of UI inspiration although subfolders are not supported 2/ Tab bar: the native vertical tabs organization could allow tree management (e.g. Firefox addon Tree Style Tab). Helpful for those who open a lot of tabs and intend to quickly understand how tabs relate and close/collapse them accordingly. 3/ Contextual websearches within Lightning instead of Google search.
