Microsoft Launcher app (Version 6) for Android now offers dark mode

Woah. Right? No? The Launcher comes with massive visual change and performance upgrades. They now offer dark mode without which any app seems to be the runt of the litter.
Woah. Right? No? The Launcher comes with massive visual change and performance upgrades. They now offer dark mode without which any app seems to be the runt of the litter. Version 6 also has a new icon, daily wallpapers by Bing (that other search option like Google but not Google) and can now work in landscape orientation. It apparently loads faster and has reduced battery drain.
Why though?
The Launcher app gives Microsoft entry to the biggest app platform to show Windows integrating with Android. This is promising as dual screen Surface Duo running on android will be launching at the end of 2020.
