Windows 10 for phones leak shows new multitasking UI

The folks over at WindowsMania.pl have gotten their hands on a new build of Windows 10 for phones; this latest build comes with a set of UI changes and enhancements; mainly a revamped multitasking screen. The new multitasking screen shown above displays open/recent apps in a card like manner, similar to how Meego or BB10 showed them, allowing you to quickly view all your open apps at once, while presumably still swiping them away (or simply pressing "x") to close them.Those screenshots remind me of this.
