There are six timeframe options for considering a topic “New”:
But there is only one tooltip text:
I can edit the site text js.filters.new.help to change the tooltip – but again, there are six choices for the duration setting, so five of them will always get a misleading tooltip.
Latest, New, Unseen, and Unread are close concepts, and the tooltip hints are important.
Would it be feasible to build in a set of tooltip texts for New, keyed to the user’s setting?
