Apple's OS X 10.11 El Capitan was announced at this year's WWDC and has been designed around enhancing the overall experience and ease of using the new system. It builds on strong foundations of last years Yosemite release. developer previews are out now, with an official beta due for release in July.
So lets get into the facts that matter, what have Apple added in El Capitan that will make it such an improvement on Yosemite? We can take a look thanks to Imgur user Malstrom, who made a post about the changes he noticed.
Dragging one app on top of a full-screen app allows both to share the full-screen mode in a new mode called "Split View".
Split View Adjustments
When you adjust the size of one side of the Split View, the other side is blurred out, allowing you to focus.
New Button Styling
Instead of the completely flat white (#ffffff) buttons of Yosemite, El Capitan's buttons have a nice, subtle white gradient on them that makes them fit in better with their gradient toolbar background.
New Mission Control
As far as I can tell, the only things they really changed here is not blurring the desktop wallpaper, minimizing the windows up top to just labels, and removing the icons on the window previews. They also added a nice new animation to adding a new desktop.
Expanded Mission Control Desktop Previews
Upon mousing up to the new Mission Control top bar, it expands to give you a full preview image of all of your desktops.
