You know already the HtmlArea  widget? It is a Rich Text Editor based
on qooxdoo 0.7.x and comparable to the YUI widget. The new Selection API
is however only available for the new upcoming 0.8 version, but we
already started to port the HtmlArea to 0.8 (not finished yet).
So in the future the HtmlArea will make use of the new Selection API and
in the course of this the Selection API will expand and maybe there will
be support for the positioning of the caret.

Thanks for this idea. It is always good to hear what features are needed
in order to build a cool widget. I'll add this feature request to our
bugzilla to not loose this one :-)
