Hi guys:
Thanks for your reviews and time on this site. According to your suggestion, I’v made some improvement including:
* Added results from Duckduckgo. Now 4 engines included: Google, Bing, Yahoo and Duckduckgo;
* Turning pages of results;
* Shortcuts of Scrolling to Top and Scrolling to Next Page;
* Search box fixed when scrolling.
* Only two biggest engines displayed when visited for the first time.(So horizontal scrolling disappears.)
Sincerely welcome your dropping in and your comments no matter good or bad.
