Captive Portal - Status Page
How about a total of connected clients on the end of this page (Captive Portal - Status Page) ?
I always go to Services -> Captive Portal and look at "Number of users" to get this information.
There used to be one there on 2.2.x IIRC, I'll see what happened to it.
I put the count back in for users and vouchers. The commit went in, it should show up on https://redmine.pfsense.org/issues/5978 momentarily.
Well done, thanks jimp.
