Delete Ink by point control
Have you experienced the stroke deletion using the standard InkCanvas/InkTollbar against the ink deletion experience on the Sketchpad app?
The Sketchpad app give you a way more natural to delete strokes because it allows you to delete ink by single point, like an eraser on the real life.
At the moment the UWP APIs does not expose such a way of erasing strokes, you can only erase the whole stroke, and in order to achieve the ink deletion by point there is a lot of code to write as well as having the appropriate know how.
What do you think of an extended toolbar where you can have the sake Sketchpad app without writing one single line of code
