WooCommerce Development

General information for the website: We sell clothing
Kind of development: Customization of existing website
Description of requirements/features: 1) Display Product Description in Product Page
2) Display appropriate logo/text in header depending on what part of the website the user is currently in.
Extra notes: Hi,

I have a WooCommerce website that is 99% complete.
I have 2 particular areas to finish and would like a PPH-er to help me :-)

1) Display Product Description on Product Page - I *believe* some template overrides have caused this to disappear on my current version.

2) Change logo / hyperlink text in header depending on where in the site the user is / has come from.

To explain #2 further...
My shop has 2 parent categories (Clothing / Safetywear).
I'd like to show a different logo in the header depending on A) what category/product page the user is currently in OR B) what the last product/category page they visited.

For example...
If the user is in the Basket / My Account / Checkout etc. pages, it will check what the parent category of the previous page was and display the appropriate logo/text. If the previous product/category is part of Clothing, it would display the Clothing logo and vice versa.
I believe this would probably use php cookies to manage this.

I have attempted #2 on several occasions with varied success but never 100% solid.
