The link to change the category should be given at the top. After the user laboriously fills in all the fields, he notices somewhere below that he wants to put it in another category … and has to write everything from again. It makes more sense to place the link at the top. It’s best to tell the user which category it actually puts. Maybe he goes to the toilet, goes back to the computer and doesn’t know what category he’s putting it in.
I agree here! Also showing “Category” itself (at this stage user selected it already) on the ADD and EDIT listing page – would be useful!
Also it doesn’t seem like there is a lot of changes required to the current view!
