* Need a way to expose functions to JS that is more powerful than the current support for exposing the slots on a QObject. We need to be able to add functions directly to the window object so that we can expose methods directly without a containing object.

* Need a way to render block level elements directly to a QPaintDevice, specifically divs. These are divs that can be dragged out of a website onto the the desktop and will remain updated. One possibility is that the elements returned by a QWebElement search could have a paint( QPaintDevice * ) method.

* Workaround: Maybe find the bounding box of the element and paint that? Horrible hack and will not handle elements that have an alpha channel very well.

* KDE features to form widgets etc. It is not known how to integrate KDE features such as text completion with the versions of these features implemented in JS in the web page.  Currently since the AJAX mostly does not work in KHTML, the KDE versions are used.

* How do we integrate java? There are 2 ways Java is integrated, via the <embed> element or as applets via the NPAPI.  The problem with the NPAPI system is that existing Java plugins also rely on XPCOM.  <applet> is mapped atm by QWebKit to <embed>.

* Not loading the right thing when linking to other data types eg. text files, or spreadsheets.

* Plugins. WebArchiver needs access to the source so it can store it and the resources it references (images,css) and edit the dom so the references point to the local copies.  This may be possible with QWebInspector.  Could also watch things coming through QNetworkAccessManager, but this would break when there are interleaved page requests.  Perhaps KIO cache should be used to get and save these resources without reloading 2Mb web pages.
