I have seen some screen shots of an application drawer with tabs running down the right side of the screen for various categories (i.e., tools, web, games, etc.). The tabs look like the index dividers in a notebook. Can anyone tell me if this is a feature of a particular launcher or it's a separate app? Is it available for stock phones, without root? I tried to find a picture to show you what I'm talking about, but, of course, now I can't find it anywhere.
