The old interaction was quite horrible. I don't think I ever really got a good use of it. It was so hard to understand what you were picking and so on. Now that we can multi-select items, let's just use this as the base of what we want to align or distribute. Clicking on canvas will now mostly be used to pick an item as reference. From now on, only the reference object will get on-canvas handle, making it very obvious how your alignment or distribution will work. I leave only an alternative picking method (with Alt or Shift-Alt pick) to add guides to objects to align or distributes, as these don't have a selection dockable. I'm also improving the selection of stacked layers by looping through them (similar as the layer selection on canvas feature) so that we can select even background layers which have a lot of layers showing above. I am planning to improve this tool even further, but this is a first step to make it actually usable within the new multi-item interaction logic.
