Belt Visualizer is a tool to highlight all belts connected to a single belt.
It supports sideloading, including onto the hoods of underground belts.
If you want to highlight a specific lane, press the highlight key again while selecting the same belt to cycle through different lanes.
Belt Visualizer only highlights belts that are connected to the origin highlighted belt.
Modded belt connectables like loaders and linked belts get highlighted as well. This example uses notnotmelon's fork of Factorissimo 2.
