Does Android retain market tags on apps? I'm not sure that I've ever seen tags like "games" or "utilities" and such on applications anywhere within the operating system. I think that would be a great thing to have, though... and I'm kinda surprised if it doesn't exist somewhere but I'm not aware of it. As for launchers that eat battery life--most of the best ones don't. LauncherPro is what I use and it doesn't... mainly your battery vampires tend to be the widgets that run on top of the launchers, not the launchers.
