This looks like a great plugin, but I'd like to use it more for admins (and maybe authors) to be able to see when each other are on-line, rather than displaying it out to the world. The two functions seem to be tied, meaning I have to have the frontend showing before the backend functions. Can I just use the backend? Also, can the backend have similar display options? It takes up a HUGE amount of space on the Dashboard, and I didn't see a way to configure that.
Also, maybe I was doing something wrong, but it showed me as being off-line while I was logged in working on it.
