Apologies if this has already been suggested, but I couldn't find it anywhere.

I just accidentally deleted the wishlist category for a pet's TC instead of opening the category. I know, stupid mistake on my part, but a dialog box asking me to confirm the deletion would have saved my absent-minded self from a hassle ^X^;

EDIT:

Oh, I see the items went into my unsorted category. Fortunately, I didn't have much in there... but the confirmation would still help in case I did!

Yes...please....this should've been added in the beginning ......

Definite support. :/
