Is it possible to have in the Listing tab, the comment column displayed? (or any other custom field)? It will be useful when somebody wants to send just a the table as copy/paste in a file. For instance, the QA teams are sending this kind of tables to developer oversea.
Also an export to xls feature it will be nice ;)

The ability to add custom columns will be in the next major release. See bug 73 for that. As for displaying the comment column, are you talking just about the first one/initial report?

And XML export is available from the search result page. I do not know how to form an XLS file (I can look into it), but I'm pretty sure Excel can import an XML file.

Yes. I'm talking about the first report only, not all the replies.
