8. Take out from theader edit and delete button

8. The canvas is well-structured hierarchically. The only thing I would change in this part is to put the edit and delete buttons in a list (there is a logical relationship) and take them out of the header, because when I navigate through headers it reads: "heading level 4 Inventory collection Edit Inventory collection Button Delete Inventory collection heading level 3 Button".
