Bifrost.XAML.Phone (nuget): Controls: ProgressIndicator - imagine a progress bar on steroids.  In addition to maximum/minimum/value, you can provider a target value and target label to, for example, display today's target for a budget.  RingSlice - Based heavily on the RingSlice control from WinRTXamlToolkit.  This version fixes a UI digest issue I ran into on device, adds support for drawing a full circle, and handles angles > 360°  PercentRingSlice - Based on the RingSlice control, but this works more like a progress bar.  You provide the maximum/minimum/value and the control handles figuring out the necessary arc angles.  SplitView - Modeled after the WIndows 10 SplitView control, this can be used now and will provide very little effort to move over to the Windows 10 control once it is ready.  It also includes a few bonus features that the Windows 10 control will not: users can swipe in from the side to open the panel (no need to reach for that hamburger icon), a header bar styled similar to the Windows 10 apps is included here, provide your own string Header or custom HeaderTemplate to customize the content displayed next to the menu icon.
