I managed to reverse engineer one of the existing themes and this is the best I could come up with. It would look a lot more like stock Android if I could get rid of the icon labels on the dock, but I can't figure out how. The All Apps view would look better if I could make the tab background transparent, but I can't figure out where that background is coming from. Also, the clock icon never changes even though I replaced it. Looks like none of the themes can replace the clock icon, so that's an LG bug. Anyway, I like that it looks a lot less cartooney and at least I didn't give up like I usually do!
