WebPiece is a tiny Web browser software, which runs on Apple Macintosh OSX 10.7 Lion. Ever since WWW emerged, Web browser has become one of the most important application platforms and it is still growing. But people have to use their web browser for tiny and non-critical mission pages. These pages occupy web browser's tabs, windows and bookmarks, which can be really irritating. Some web pages like Twitter or Facebook have nice native applications that are provided from them or 3rd parties. So, while you can use those web services out of your web browser, most tiny HTML pages do not provide native applications. WebPiece is designed for drive tiny web pages like time card application, SPAM killer CGI, etc... So, get rid of those things from your favorite web browser and register into WebPiece with URL list window. WebPiece also provides separate cookie spaces for each web windows.
