The ramp-up to Apple's WWDC this June has begun, with reports circulating about the goodies the company will include in the next generation of its desktop and mobile operating systems. The latest revelations include macOS support for the iPad as an auxiliary display, and iOS support for multiple windows within apps. There are a number of third-party products on the market to add an iPad as a second display for a Mac, but the feature reportedly will become native to Apple's desktops and laptops with the next version of macOS, version 10.15.
