OS x yosemite and ios 8
Maps, safari and mail have all been redesigned, removing a lot of the elements not needed giving more space for content. The new mail app lets you make changes, draw arrows, create magnifying highlighters and so on directly in the compose window. if you draw an arrow it will identify the object as an arrow and replace your ugly hand drawn arrow with a proper arrow that you then again can rotate, bend and manipulate to your need. This is going to be a cool and effective function. The notifications bar now has widgets, the same or similar widgets are also going to be a part of iOS. The notification center on iOS will also feature interactive notifications, allowing you to reply on messages or calendar invites right from the lock screen, notification center or the top notification bar when these come through.
