At present, when you click on, for example, "Others" under "Page URL" in the "User Actions" section, all the menu tabs disappear. This shouldn't happen, and it would be nice to see subtabs with the other sections in that group (e.g. File Type and Visits Duration).

I suspect that this is going to need quite a bit of fiddling with the URL formats to achieve, but it would be worth doing at some point.
