We are planning on including additional ways of filtering data. For example we where going to include the ability to select tags as part of a filter but we could also include the ability to select one or more folders in a group, but I don't think that completely answers your question.
I'm actually curious to hear more on how you're using the trace matrix or the report. In my mind the matrix table is good for quickly seeing items that are missing a relationship. So for example in my project it could be important to have each Feature trace to a Test Case to ensure 100% coverage. The matrix would show any gaps. Your comment seemed to indicate that you just want to see a summary of only the items that already have a relationship.
The reason I bring this up is because traceability in general is such an important part of RM and Contour that we are planning on separating out a whole relationships page. This will include a graphical trace diagram, a trace tree and the matrix. As well I could see including features like what you're asking where you can customize the view to show relevant items. Could you provide a couple of quick scenarios on how your team uses relationships to manage data?
As far as the report goes this is very customizable. It should be possible to produce a report like what you seeking in Contour today. I'll double check but basically you're looking to combine the SRS report with the Traceability report?
