Right... so I changed the Rules sections and added a new rule to `highlight in red`the dead miner, before it reboots the dead miner. Now all my miners are permanently Red highlight :-)...
1. I`d love any ideas as to how to remove the Red Highlight (automatically) once the system detects that the Miners are back on line.
You could create a rule to turn it back to "none" highlights. I would suggest a trigger of Hashrate greater than X, then action to change highlight back to "none".
I know it's a bit hidden, but it's actually possible to "clean" away the color by going to the toolbar: Appearance -> Highlight Miners -> Clear All.
