A recent leak has revealed a new tile resizing animation in Windows 10 Mobile Redstone Build 14278 that is under internal testing. The animation shows Tiles fading in and out while the resizing operation takes place. Check the Cortana tile in action in the video below.

It is certainly not a ground-breaking new feature added by Microsoft to Windows 10 Mobile Redstone, while we wait for many tipped to us by our sources. But this can well be the harbinger of meaty UI changes coming in near-future with Redstone Preview builds.

Windows Insiders rocking a new Windows 10 Mobile devices are currently on Redstone Build 14267.1004 and Microsoft released PC Build 14271 last to Windows Insiders. So, may be we will see Build 14278 or even a higher build soon getting pushed to Insiders. BuildFeed tells us that Build 14278 has been under testing for 3 days already.

What else you think Microsoft should work on to change with Redstone in terms of UI revamp. Do let us know.
