We introduced jQuery UI to Cotonti in purpose of standardization: to have a solid toolkit for making widgets and using effects. But unfortunately the library quality is below our expectations for 3 reasons:Bandwidth. This is mostly solved by using a new resource compression tool.
Inferiority. In fact the toolkit is incomplete and you still need a lot of third-party widgets.
Instability. Currently there is a hundred of unfixed bugs and yet more to come. I tried using 1.6rc6 and it is even worse than 1.6rc5.
I'm very disappointed about this, but seems like we have to get rid of jQuery UI until it gets a proper quality.
May the Source be with you!
