"Keep me logged in" option

"Keep me logged in" option

Having to sign in every other time I access Zoho is a real pain.  Please change the way the "Keep me logged in" sign in option works. This should be a user preferences option that gives the user control over the time period.  I would suggest 
a control that allows the user to specify a number of hours between 0 and 23, AND a number of days between 0 and 365.   Google, Live, Yahoo and other email providers support extended and automatic re-login times.  Zoho should also remember and reuse the "Keep me logged in" check box indicator until changed during a successful login.
