See what’s slowing your factory down.

Bottleneck adds status lights to assembling machines, furnaces, mining drills, pumpjacks, and chemical plants. Find stalled production without opening each machine.

Default indicators:
- Green — the machine is working.
- Yellow — production is blocked by its output.
- Red — production is waiting for inputs.

Customize the indicator colors in the mod settings to suit your preferences or improve visibility.

Controls:
Press Shift + Alt + L to toggle the lights.

Performance:
Adjust how many machines are checked per tick. Higher values refresh indicators faster but require more CPU time; lower values spread the work over a longer period.
