I check for new filters every few days, and sometimes I don't want to preview a new filter in the download window because I can tell at a glance it won't suit my needs. In the main window, there's no indication of which filter is new or not, and since I have so many filters, it's a pain to click every single one just to get the numbers in parentheses to go down. It would be nice to have an option to mark all new filters as viewed in both the "Download New Filters" and the regular FF windows.
