BASIC CATEGORY BLOCKS

So far, I don't see a way to add a block that displays subcategories (with images) and not the products.  That seems pretty basic.  So here are some basic and useful suggestions for blocks:

- CATEGORY BLOCK (displays Categories, not products)
- SUBCATEGORY BLOCK
- PRODUCT BLOCK FROM SELECTED CATEGORY (you can choose the category[s] to display products from)
- RELATED PRODUCTS BLOCK(very useful for product pages)
- COUPON DISPLAY BLOCK (you can select coupons to display from either the block or in the coupon creation section, like a check box for public or non-exclusive coupons or something)

Thank you!  Im really struggling with the new builder's limitations. :(
