Blocks can be arranged to suit your needs. You can move Blocks around the canvas area and you can bring the Block to the front or send it to the back of other Blocks.
There are other options, not immediately apparent, for example, rotating Blocks around a Block, in a sort of roundabout fashion, or you could randomly scatter Blocks around the canvas. Sometimes a random scatter can fire up a new idea.
When arranging Blocks, you must first select the Blocks you want to affect. Some operations can be done on one Block, while others require more than one Block, ie: Rotate Blocks.
