Overlapping lines in sketches

Anyone come up with a good way of finding those pesky overlapping/duplicate lines in sketches?  I rectangle select over suspected lines and delete if there happen to be 2 lines.

Would be so nice if overlapping lines automatically highlighted pink, like the black, blue, red line colors now. 

Someone made SPR 984957, asking for a special tool to detect them.  I'd rather they just highlight...
