Handoff is a really useful feature (when it works).<p>Also SL mamed Expose (that weird non-proportional grid view) that was reverted to the Leopard-style in Mission Control (of which Mavericks&#x2F;Yosemite had the best implementation, and they&#x27;ve now broken its utility in ElCap thanks to hiding thumbnails by default. FFS.)<p>But apart from that... I think I preferred the Apple apps back in 2009-or-so.<p>To be honest, I think the latest Apple release cycles have been more about &quot;remove a feature so that we can add it in again and sell it to our users again&quot;. Think multi-monitor support, something that worked perfectly in SL and earlier, and then broke fantastically with the full screen apps in .. Lion? ML? One of the two.
