easing: "swing", 
duration: 1000 
}, options, additions); 
options.content.stop(true, true).animate({ 
widthvalue: options.processValue 
}, options); 
} 
} 
}); 
})(jQuery);

widget主要是处理ui层面的,实用与否只有用了才知道,widget可以利用jQuery已经存在的css framework。利用themeRoller,可以很轻松的换肤。至于说功能,可以在用户反馈后再慢慢完善。
这个progressbar本身是继承自jQuery ui progressbar的。因为开源,如果自己有好的想法,自己也可以去增加自己需要的功能。
