On the front page, the modification timestamps link directly to the answer that was posted/edited. The timestamps on the "active" tab for a tag don't, however.
I often find myself checking on the active tabs on some of my favorite tags, as updates of the less-trafficked tags tend to get drowned on the front page. It would be quite nice if the timestamps here would have the same behavior as the ones on the front page, so I can easily get to the change.
In summary, I think this should be added because
- It's convenient.
- It's consistent with the behavior on the front page.
- It should be a pretty straightforward thing to add.
EDIT: I had originally posted this as a bug because I thought it used to work this way before. I'm not sure if that's the case, though, so I'm changing it to a feature request. Feel free to change it back if I'm mistaken.
