lots of toolkits are available today. They are cool but what we need is not necessarly cool effects (although some could help) but a framework that allows us to create our own widgets. So the question is not which toolkit to use but more which kind of design patterns or standard in writing a widget. There are a few basic issues that are solved in these toolkits (like how to load libraries, how to link a html element and a JS class, what format to use for a class etc.) and the community should focus first on these points instead of trying to offer toolkits thaht have been writing for a specific context (i can’t see any that I can apply in my applications). We need design patterns and widget coding guidelines, not toolkits.. In the meantime, the only library I find useful – as a standard – is prototype.js …
