ModuleInserterSimplified VS PipeVisualizer

As for the module planner, consider checking out Module Inserter Simplified. It's a bit more streamlined.

Bottleneck, constructron, enhanced_map_colors, even_distribution_lite, fastremovetiles, module_inserter_Simplefied, quickmaptag, realisticores, uranium_geiger, VehicleSnap, WoodDoesBurn

Module Inserter Extended and Module Inserter Simplified - Pretty much what they say on the tin, they add extra tools for more easily shoving modules into everything. I used to use Simplified, but the altered beacons in SE made the flexibility of Extended very useful, and both are very easy to use (though if you're using Extended and often adjust your presets, remember to click the dang check box in the popup UI before closing it!)

Also the excellent Module Inserter Simplified, Factory Search and various other cool mods.

Module Inserter Simplified (or Module Inserter) - Allows to insert modules with bots after buildings are already built.

If you add my other mod: https://mods.factorio.com/mod/ModuleInserterSimplified

I recommend Module Inserter Simplified (newer, simple interface) or Module Inserter (older, different configuration style).

Module Inserter Simplified lets you simply drag around buildings to add or remove the selected module.

If you're OK with mods then Module Inserter Simplified can let you request modules for buildings from the map.

If you're open to using a mod to troubleshoot, I like Pipe Visualizer - Factorio Mods

Pipe Visualizer is a god-send.

Pipe visualizer: https://mods.factorio.com/mod/PipeVisualizer

PipeVisualizer - Highlights pipes of different fluids!

PipeVisualizer can be helpful when debugging pipes.

Something like Pipe Visualizer but for wires?

Honestly, I prefer Pipe Visualizer for pipes. The colorful lines are easier on my eyes to see.
