Ok, here is a new project on GitHub: ep_activepads. It is a plugin for superb collaborative text editor etherpad-lite that lists all pads people are working on right now. It is highly inspired by ep_adminpads plugin.
What I would like to add alter is data auto update, probably with the simple timer on client side.
To install the plugin, clone it into node_modules/ep_activepads folder of your etherpad installation, terminal there and do npm install.
