Every time someone invents another framework, 1000s of hours are lost to rewriting these widgets - colour pickers, date pickers, drop-downs, combo-boxes etc etc. And that's before people complain about lack of flexibility and all the missing features their predecessors have accrued over time. More wasted time as people try to get to grips with yet another style of configuration, operation and tweaking to fit real world use cases.<p>I'm all for innovation and advancing the state of the art, but there has got to be a better way of dealing with these basic components. All we're doing here is creating projects for those with time on their hands, frustrating those with none, and keeping StackOverflow in business.
