There are web pages, like e.g. the webmail frontend to Lotus Notes, that expire
after some time without user interaction. In the particular case of Lotus Notes,
the user is required to log on again after some time. This is quite cumbersome
and certainly a misfeature of Lotus Notes, not Epiphany. 
A workaround for such pages could be an auto-reload feature; if toggled on, this
might tell the browser to just reload the current web site after some
(user-specifiable) interval.

The suggestion is to have an autoreload toggle button in each tab (perhaps next
to the 'close'-button. If pressed, it automatically reloads the respective page
after some minutes. For people who have to read mail using web frontends with
the described misbehaviour this would save dozens of manual log-ons a day.
