Hi dragly,
as I asked at the diskusjon.no-forum:
«Bruker den trafikantens gamle eller nye API? Dersom nye, er det åpent for alle å bruke nå? Var prosessen med å få lov av trafikanten å bruke API-et problemfri?»

I have also a problem to report. I can't add a travel («reise») to my favorites, that just works for real time («sanntid») searches. But under most recent («Nylige søk»), both categories are listed.

Great application, I was tempted to make my own Maemo client, but since Trafikanten is/are/was in the process of changing API, my plan was to wait until this autumn, but I think your client saved me the trubble.
