There's one thing that annoys the hell out of me about this ROM. It seems to have a task-killer of some kind and it is way too aggressive for my taste. What I mean is, it kills each app as soon as it loses focus. For example, I'm playing Angry Birds, I just want to check time so I hit "Home", look at the time and then resume playing – at this point the app is already killed and it has to start up again. Or I'm reading an ebook with FBReader, I want to turn off wifi and then FBReader has to start up again and load the book etc. I think you can find other examples yourselves. And I'm pretty sure this causes the battery to drain faster, rather than slower.
I was looking for a setting related to this but I can't seem to find one.
