There are lots of things in the new version, but just because your random wish isn't there it's "not much"? Give me a break. Besides, you can already do that with DroidWall or any other firewall in the play store.
Er, where did I say that? My "random wish" was one of the new features they announced that I am glad they included.
There are plenty of new features in 4.3, but they're all developer-centric. Absolutely nothing wrong with that, of course, but it means it isn't so exciting for many people. Especially as few people can afford to target these new features right now, given that their potential market of 4.3 users is tiny.
