Carsten, I agree with your list. Plus some of mine:

1. Full functional sound system. This is probably the same as your wish number 2 above. I find that some music/sounds (especially MIDI sounds) in certain games blows the sound system and it has to be reset.

2. Increase max Dynamic Heap Size configuration parameter from 4 MBytes to 8 MBytes.

3. Have a Landscape fullscreen (one that truly fills the screen like the existing Portrait fullscreen,...a good example is the Zodiac landscape mode).

I'm sure there's more. I'll list here when I think of them.
