According to James Wen's paper about Post-Valued Recall Web Pages[1], temporal
breakdown of the browsing history within a day can be important to find back pages: 

"It was noticed that a user's desire to simplify a complex hypertextual space
into a simpler linear space is often exhibited in the user's replies that are
temporally-based--e.g., "Saw this page around lunch time." As a linear and
familiar notion, time is perhaps the most powerful parameter used to localize a
search space. Both the Internet Explorer and Netscape Internet browsers offer
temporally-based history lists. Neither browser has anything more sophisticated
than a textual list. In addition, Internet Explorer does not allow temporal
breakdown within a day, thus virtually excluding the retracing of surf sessions
that rarely last for long, continuous periods."

Thinking about how to implement this most efficiently in Epiphany, I came to the
conclusion that it should be possible to sort the listed history items on time.
This means adding a 'Time seen' column (as leftmost?) and use this as default
sorting method. The history should be sortable by Title and Address by clicking
on the corresponding column header.
