Music player, tutorial messages and skill points

[Xerduntis]

I completed the game yesterday, but I'm so in love with it, that I keep replaying the missions.
What I noticed so far is, that I miss an option to disable the tutorial messages which keep popping up when you revisit a crime scene. The same goes for the message to spend skill points, even though you maxed all the skills out.
I also noticed that the music player has all the options one would need, but the controls don't seem to be working properly. I tried shuffle, I tried to sort by genre, but it always plays just one song and then stops. Likewise, I would also love to have a feature that allows you to play only the songs you like (I assume that's what the checkboxes are for?).
Speaking about conveniences, it would also be helpful to have the tablet show you which areas you completed, especially for the last two huge maps. Maybe show the progress on an overview map, divided in different areas, on the tablet? I mean, we run around with the tablet anyway ;)
