I notice there is a graphical anomoly while hovering over the power meter while it's charing. The power read is not in front of the text on the speed/energy upgrades (the background of the window seems fine).

Lastly, it seems while the digital miner is charging, you are unable to set a Config, it bounces you out of the miner's menu system. Once the rig is at full power supply, it's ok.

Both of these issues have been fixed, and will be available in v7 very soon :)
