Docking blocks in a document allows unnecessary blocks to be minimized and stored out of the way in a dock, making it easier to access important blocks. To dock a block, click on it and drag it to the dock area, and to undock a block either click the undock button when hovering over the block or click in an empty space in the dock to undock all blocks. Docking blocks organizes a document by removing non-essential blocks from the main workspace.
