Master/slave connection message
The connection ok/disconnect message is very small. Could there be an option to make it large (perhaps in Settings>Network? so those who need to see can easily see it).
Also the Master might need to check all slaves are connected, so a list of the connected iPads would be useful.
The next version will have a larger alert for connection info.
The problem is that iOS doesn't release the names of the connected iPads right away. Sometimes it thinks things are connected when they aren't. Very weird. There is a list of what iOS thinks is connected. In the Network Window, there's a ? mark. Press it to see all connected iPads.
