MSPowerUser.com is reporting an intriguing finding in the latest build of Windows 10 Redstone: "new APIs for a RadialController which is likely similar to the app-specific one in the OneNote app."
The build also includes a new Ink Toolbar control toolbar.
Both of these new features should make it easier for developers to add radial menus and annotation to their applications.
The site doesn't offer many details beyond this, so any Windows Insiders familiar with the APIs are encouraged to offer their insights in the comments section below.
