Suggestion:

Have both a light and a dark theme. Other apps like FMobi have something like that and I'd really love it because a) it improves battery life b) the dark theme is sometimes better visible.

Ps. Whats up with some people yelling "here we go again" or something like that the second someone asks about the Wazapp progress. Why shouldn't we be allowed to ask if the app still has a lot of bugs or something.. What use is a forum if not to discuss...
