It would be great if Epiphany remembered the different values the user entered
in input fields of websites.

For example, when arriving to the login page of his webmail, on the login input
field, the user types the first letters of his username.  Then, Epiphany pops a
dropdown list of the values he already had entered before.

Other information:
Just like Firefox, Internet Explorer, Opera and the other borwsers do.  It saves
some time, especially when the values entered contains a lot of characters
(email addresses, long usernames, homepage or website addresses...).
