Lightning Launcher

**This is an old revision of the document!** ----

==== Unidirectional desktop ==== Unlike common Android launchers (that slide desktops sideways) LL is like a canvas that can be expanded in any direction. Users will normally only see those desktops that contain items, but of course blank desktops that are both above/below and to the left/right of a non-empty desktop will shiw as well. On top of this, users can zoom desktops, and so make all desktops visible at once. Zooming can be disabled, and scrolling can be limited with stop points.
