I've meanwhile done 2 commercial  web projects with it, and development goes
amazingly fast.

The start of webwidgets which I committed earlier have been enhanced very much meanwhile,
and I will publish the enhancements in the near future, together with a demo
application.

The template loader/component is in fact the workhorse doing the bulk of the
work and in combination with bootstrap CSS you can have an application up and running
in no time.

But the biggest help have been the dataset classes, combined with a REST or
Remobjects Data Abstract backend..

At least TJSArray and TJSPromise are on my list for replacement with generic
types, as well as TTypedArray and friends. For backwards compatibility I'll
keep the current classes as specializations with JSValue.

Do you have other classes in mind that could be usefully replaced/enhanced with 
a generic variant?
