@gidzz...how?
As you can see in the last screenshot, the settings menu allows for horizontal scrolling, which looks a bit odd. Also, in portrait mode the swedish localisation of the checkbox about FMTX is wider than the popup menu (so the horizontal scrolling is in fact necessary here). It'd be better to make the checkbox label multi-line (if possible?).
A minor localisation issue: the swedish localisation of "Now Playing" is currently "Nu spelande", but in the stock media player the translation is "Nu spelas" (which sounds much better as well)..
Finally, a feature suggestion: a song queue system and the possibility to queue songs in the playlist for playing. This is probably the most important feature I've missed in the maemo media player compared to desktop music players.
The most important thing has been missed here, I am talking about checking newly added songs or videos. In the stock player yellow information appears when opening it after adding new songs, I meant: That function in OMP is missing.. After set OMP as default music player, I must open gallery to triger that check for new files. I think that is really important, and must be implemented.
