We have been using the new user interface without "Add to Watch List" on a search page for some weeks now.
I am finding it so frustrating!
I can accept clicking on an item before being able to add it to my watch list, even though that adds time to what should be a simple task.
However, once I am viewing the item, I have to wait until all the advertisements have displayed before the position of the Add the Watch list button settles down.
I find myself regularly clicking on Place Bid or Buy it Now by mistake as the buttons move down the screen.
It takes up to seven seconds for the full page to paint for me, so this adds more time to a simple task.
This new interface design is a backwards step in usability.
