1st of all, I thank you for this very useful application.
Recently, I've upgraded it but haven't tested it before going hiking... Unfortunately, I realized too late that the 'onlinemapsources.xml' has also been updated in the same time, loosing my own online maps connection information. Editing, copying from backup and paste to current file isn't very easy on the hike, when walking (it's possible, I did it).
I know that I've agreed when the app told me if I also wanted to upgrade this file... but at this time, I didn't remember that I add some personal online maps.
So, for me and all people which have brain memory leaks, is it possible to manage an 'onlinemapsources.xml' file and a 'CustomizedOnlineMapSources.xml' file? Of course, the customized file won't never be automatically updated by the app...
Thank you again for your work, very impressive!
Olivier.
