I was among to people that asked for this feature! Thank you for creating it!. It is a huge step in the right direction (for me atleast).
The main goal on why I asked for this feature was simple: many trips & vacations are create in BaseCamp. As a MyRouteApp user I was constantly confronted with files I could not use (I had to use basecamp and export all track & routes by hand).
Anyhow, although this is much better, I still have two requests.
1. Keep original track/route name as they are stored in the GPX files (something like (FileName+RouteName)
2. Import routes and tracks in one go (far less important, but would be nice).
