Google Adds Expand and Collapse Button for Show Options in SERP

Google is the search engine that often updates its SERP with more features on a regular basis even a small change is a big update in the industry. Adding to this update, I would like to add that today when searching I suddenly noticed that a small addition of the Expand and Collapse button for the “Show Options” link. Please refer to the below screenshot,

Expand Mode:

Collapse Mode:

I’m sure Google is still working to fix the button at the right place and make sure the + symbol changes to – when collapsed or expanded.

I feel this would help visitors to better understand the usage of the “Show Options” feature in Google which makes search even more better.
