Tag pages lack sorting and filtering #1963
Description
The search-results page has buttons for sorting and also includes the filter widget (example). The tag page (example) lacks these options. In a sense, the tags page is sort of a specialized search, so it feels odd that we don't have these options there too -- people who want to sort a tag have to resort to searching for the string instead.
The search-results page didn't originally have these features and we added them later. I assume their absence on the tags page was an oversight and not that there's some deeper issue here.
