support for session cookies
From a security perspective, as the administrator of a Mattermost server i would like to be able to set a system-wide property to force the use of session-cookies for the web interface. Since computers can be shared i find it undesirable that you're automatically logged in again as is the case currently.
But i guess in the end you'll also get users complaining that they want the end user to be able to choose. So i guess the ultimate solution would be a property for session cookies that you can set to 'force' (user is not able to choose), 'optional' (user can choose) or 'disabled' (if you find that all users must be logged in at all times.
