I would love to see a disconnect confirmation prompt before the web client exits. I've accidentally closed the window or hit back or reload more than enough times for it to be annoying and I lose those precious logs. You should be able to put the following function in the var onUnloadHandler = function() area of the client.js before the emit @quit line:
var confirmOnPageExit = function (e)
{
// If we haven't been passed the event get the window.event
e = e
