* Can the Gecko engine be used to get the width information of some HTML elements (such as table,tr,td)
* There was a discussion about interfaces allowing multiple presshells. The writer is for the idea and believes this issue should be cleared up.
* The writer is seeking instructions on how to fix the table border color quirk that makes the border color dependent on the background. The quirk is a pure NN4.6 quirk.
* The writer is trying to convert nsHTMLReflowState into a base class.
* A few changes have been made to the reflow branch.
* There was a discussion on CSS layout behavior which was about faux columns with a mix of undefined and fix width columns.
* There was a question on what modifications should be done to deactivate a ComboBox from Mozilla.
