eBay is adding an additional "Watch This Item" button to the listing page.  Why is this important?  If the buyer has their preferences set to receive the notification, and they are watching an item you are selling, eBay will send them emails to remind them to bid before it expires.  This additional encouragement to place a bid can put money in your pocket! 
 
It's interesting that eBay has a Buyer Experience Team?  Has anyone ever been asked about their buyer experience???  Here are the details about this enhancement:
 
Hi everyone, I'm Subha Shetty with eBay's Buyer Experience team. In the next week, we're making a few small changes that we think will make the item page (the page that displays a listing), a bit easier to use.

The changes include:

-An additional "Watch this item" button - Millions of items are added to buyers' Watch lists every day! We're keeping the existing link where it is in the top section of the page, but, as a convenience to buyers, we're adding a new button which will be placed at the bottom of the page. Now they won't have to scroll all the way back to the top after they've reviewed the important details of the listing.

-Bright blue buttons for Bid, Buy It Now, and Best Offer - The eye-catching color will make these important features stand out a little more.

-Minor layout changes - We've cleaned up the bottom of the item page a bit to make information such as the shipping details, payment methods, and return policies easier to read.

Sincerely,

Subha Shetty
Product Manager, Buyer Experience Team
