Like the style of the Google search widget on ICS?
Then you should try "Simple Search Widget"! It looks like the standard Android 4.0 search widget but you can change the search provider to any site you want: Wikipedia Google Bing Amazon or anything* else!


Features:
• Changable search provider
• Type directly in the widget no need to open another app
• Looks like the standard search widget
• Dark white or none border
• Text color changeable
• Default text changeable
• Resizable widget
• No scary permissions


CM Security users: No matter what some bogus "virus scanner" apps say the app does not contain any kind of virus or malware. Apparently removing your app icon from the launcher is such a suspicious behaviour that some virus scanner apps report this app as dangerous. That's total nonsense and you should uninstall such useless scanners instead...


* currently only sites which put the search word at the end of the URL are supported like Wikipedia Google and many more. Other sites might be supported in an upcoming version
