review list page headings are unclear and undocumented

[Martin Pool]

https://code.edge.launchpad.net/bzr/+activereviews shows the reviews separated out by workflow state, but I think it is not clear what combinations of values on the mp cause it to go into a different heading. The sorting depends on fields not shown in the records on this page, including the overall mp state, whether a review is requested from me or from a team I belong to.

I think this causes a problem that people can't work out which reviews they should actually work on, or how to get things off the top of the list, therefore it's less effective as a workflow tool.

Some things that might help:

 * Define the meaning of all the headings in a help page, and link to it from this page
 * Making the header text more directly describe what reviews are included there, so for example rather than "requested reviews I can do", make it "needs review by my teams"
 * ... or, put this information into a subheading in small print
 * Or make sure that all the fields that go into calculating the category are visible on this page (though that might cause bloat)

I think at least documenting it would be a cheap improvement
