Needs spaces (parent.height * 1.1). Same for above.

Needs space (z: -1)

width and height as multiples of 1.1 should be good, as you had done above. Also space needed.

Space needed. Refer above.

Empty line not needed here.

Empty line not needed here.

Space needed (items.area.count !== 0)

Space needed (items.area.itemAt(items.itemIndex).selected = false)

Space needed (items.area = answer)

Space needed (items.area = pocket)

Space needed.

Space needed, and remove extra space, if(items.area.count !==0) {

Empty line not needed.

Space needed. Same for the statement below.

Since you were already using if-else statements above, can you maintain the consistency by replacing the switch case statements with if-else?

Extra blank line not needed.

Space needed on left of != operator.

Space needed.

Space needed after = operator.

Space needed

Empty line not needed.

Space needed on sides of = operator

Empty line not needed.

One extra empty line not needed.

Space needed on left of = operator.

One extra empty line not needed.

I first tried if-else but that took a lot of lines. Thus, I find switch more consistent than if-else. still, if you want, I will implement it.

spaces before and after : symbol.

space before {

Well, as far as I can see, the case statements will just be replaced with the if conditional statements. So, the number of lines should technically be around same :) You can once implement it and check ;)
