Quick Small changes on Magento 2 website

2. On the "checkout/cart " page, for item description, show "SKU#" and "size+Authentic Persian+ Name+rug" . 3. On the "checkout" page. the same info as above under "order Summary" 4. On the "checkout/cart" pg, can we have "Apply Discount Code" expanded as default? 5. On the "Checkout" pg, need to have an input area for "customer comment/note". My son tried to install one, but was not able to place it properly. prefer one similar to this site: [login to view URL] under order summary. 6. On the "Checkout" pg, please add a title for return policy listed on the bottom of the page. 7. When an invoice issued after an order, show item description similar to item#2 above and show "return Policy" on the bottom of the page. To match the present invoice format. Special Note : Do not apply offer before read all points and budget please. do not waste time both side. Budget 12$ Thank you
