Am interested in purchasing your plugin "Authentication - Session Limit" - I just watched the video and it seems like once a user is logged in to their maximum number of sessions, they cannot log in to any more. I was wondering if you could create an option for admins to allow a maximum number of devices but log a user out of the oldest session once they log in to a new session? Ie. if they log in (in order) to 3 devices A, B & C, and then log into D, the system will log them out of device A.
Also, could you set it so that a user can view what sessions (or devices) they're logged into and log out of specific sessions (devices)? This does sound like a whole new plugin but would be very useful no doubt for my site and probably a whole lot of other Joomla community sites! Maybe User Session Manager could be a good title for this plugin?
