The move tool is particularly useful when you need to move elements around a canvas.
Let’s assume I had a blank canvas, and have pasted a few images such as a logo and a few icons but they are positioned incorrectly.
As you can see, my canvas is a mess and will require re-organisation. At this stage the move tool comes into its own.
In order to reorganise, select the appropriate layer and use the move tool to position each element where you so wish.
Once the layer is selected, move each element accordingly until all aspects are well positioned. You should be able to get your canvas to look well organised and professionally laid out.
