A large Status Monitor I use to keep an eye on my factory without needing to run to each section to visually inspect.
Features:
Alerts & Audio Alerts, Power Levels & Fuel Status, Controlled Reactor Reload Cycle & Indicator, Material Belt Levels, Research Status, Drone Status & Automatic Addition and Remote Resource Status & Completion Indicator
