A new update to Microsoft's Sticky Notes for Windows 10 is now available to Windows Insiders on the Fast ring. Though small, the update contains some performance improvements, along with UI tweaks that bring a smaller minimum windows size.
From Sticky Notes engineering manager Donovan Lange on Twitter:
And there you have it! While there aren't any astounding new features as part of the update, performance should hopefully be smoother and the new minimum size should make things easier to use on smaller screens.
