I have added yet another potentially useful overlay to the suite which can be seen
on my site HERE.
You need to be logged in to see it though, you can use the following credentials for temporary access.
USER: fred
PASS: george
You need to look for the button in the header named 'Online', this will provide an overlay of the Who's Online page (restricted output).
A couple of people had mentioned to me that it would be nice to have easier access to this useful feature.
It will be included in the next release, which in reality will be the release candidate (as I have had no problems reported within the current beta).
