I might have overseen it.
But I would appreciate a filter functionality (Up-to-date, Locally Modified, etc.) in the cvs status (summary) report, which would only show the files with the corresponding status. Eventually the filter string/text could be entered in the same manner as it already exists for the search functionality in the same window.
A console equivalent would be something like this:
user@computer:~/prj/src/module$ cvs status | grep "Locally Modified" | less
where "Locally Modified" is the filter string/text.
