We have 6k products and each product has an IsActive field which determines the product's visibility in the website. To give an example, today we needed to make ~350 products invisible so we wrote a program using Kentico API. I heard Kentico 7 will mainly specialize on UI, so it might be a great idea to extend operations under the "List" section of a document so that we could implement the operation I described above directly from the CMSDesk.
