In the User profile options in the preferences, we have the checkbox: "Remember my login on this browser (for a maximum of 30 days)"
Why ? Does anyone use that ? What's wrong with checkbox on the Login page ? Is it just that we don't persist the 'last' choice on the login page ?
Seems rather overkill to me, definitely clutters the preferences and possibly it is confusing to users ?
