Now this is interesting and good news, at least for me:

Question on Twitter:
"Timucin Uzun ‏@TimucinUzun 8. marraskuuta
@JollaHQ what will happen if you use a black picture with ambience?"

Jolla´s answer:
"Jolla ‏@JollaHQ 1 h
@TimucinUzun You get a black background."

While I like the user interface and the Ambience-feature, I sometimes feel that the display can get a bit crowded or messy. I can also see that some people who are accustomed to the clear colours and structures in other operating systems can be put off by the look of Sailfish. It is really nice to know that you can have a clear, black blackground like in N9. I have speculated with the idea, but it is nice to have it confirmed.
