My set came dumped and jumbled, is there a map or layout of what goes where in the case?

Anyone give this the ultimate test and construct Ikea furniture with these bits?

The last picture shows a blue-colored extender. Is that also included? If not, why is the included extender not shown in the "product-in-use" pic?

What are the exterior dimensions of the case?

#101464. Says 100pc., shows 100, Overview 70? Same question, Ella 9/6? Wanted to buy, poor svc. if 3 plus wks. more for answer? Please answer. Thanks.

there are 100-pieces in the picture but less than 100 pieces in the detailed list. Can you give me a more specific list and a more clear picture
