When using the new pen-based route drawing with a handheld device, it happens too often that you draw something unintended in the end of the stroke. Often these are 50m to side-and-back type of "stings". While you can later get rid of them by adding waypoints and dragging, it would be far easier to have a "clean tool" to remove these automatically by a single click to the unwanted sting.
If you have ever done circuit board layout, you mau know that modern tools there allow you to "gloss" a quickly drafted routing later with few clicks. You need something similar to make pen based routing work in mobiles. I was happy with running the desktop routing in browser window in my phone as well, but this new thing has potential if polished a bit.
