Screen showing only 1 box

get the same screen as they have .

im not sure why im getting this only one box on my screen. kinda frustrating -_-

can anyone pls tell me how do i get back to the normal editor ( with lots of boxes )

thanks alot …

The one box in the middle is your canvas. It most likely shows up this way because its very small. If you make a new document and choose a bigger size, the default uncolored background will show a checkered pattern of light grey and darker grey squares, (if that’s what you mean by boxes). That just means you haven’t drawn or painted anything yet
