I've been fixing some of the map bugs. I have to say, your bug interface is excellent, and much better than OpenStreetBugs. However, a number of the bugs people are logging are describing application faults (or even hardware faults), rather than map bugs. That is understandable from a user perspective - the distinction is not obvious to the user. However, it would be very useful to have an option for someone like me going through the bugs to flag a bug as an app bug, rather than a map bug.
