Adding layers and new map sources can be done in mappero in the maps section, but that function is broken atm. I didn't manage to edit the file it is stored in by hand, but using a /etc/hosts entry to link maemo.org to my pc and some tweaking of the apache web dir, I got a custom file via the sync mechanism (-> http://vcs.maemo.org/git/maemo-mappe...configurations) into mappero. I have no idea why the Google Label overlay isn't in there, but the url from the mappero map list is still working and may be distributed (again).

Well, I would to some bug-fixing myself, but I am unable to compile the deb from sources. It seems especially hard at the moment, as some dev sources aren't available because of the ongoing repository relocation. If anyone can help me in compiling that thing, I'm willing to work on it...
