Scenes
i suspect you haven't quite got all the funky ableton lingo down yet?
in the session view, a row of clip slots, across all tracks, are called a scene. the launch button for each scene is found in the master track at the far right of session view.
the only way i know to hide all of this is to drag up the top bar of the clip/track view, which occupies the lower ~1/3 of the screen. i doubt that you've done this
maybe you're looking at the arrangement view? hit tab or the ||| icon in the upper right corner
