This seems to be relevant here. Jolla release plan for high-level features - update 6 / 7: https://lists.sailfishos.org/piperma...ay/004167.html

LTE coming to Finland, folder support coming later etc. but no mention of offline mapping or mediaplayer improvements. Don't know if everything thats planned (not promised!) for updates is listed but don't seem to be too promising (for me).
