Following red and green circuit connections is very difficult with just the highlighted 1px wires that sag and spline between objects, and a toggleable overlay on hover like the mod Circuit Visualizer would help immensely.

tl;dr
Allow color coding of input and output signal for assemblers 'set recipe', 'read contents', and 'read ingredients' signals.

06-19-2026, 07-47-38.png

What?
Currently if you want to read the ingredient items in an assembler and compare it against the recipe needed, you cannot do that ...

This is potentially useful but I can't think of how. Maybe having both a pick-up and depot station be the same station depending on conditions? Do you have an example of how you would use this?

I like this. But another issue is in mods like space exploration, there are not enough slots in the filter to get all the variants of rocks. There should be 'tags' you can also select like 'tree' or 'rock' etc that just gets everything in that category.

tl;dr
allow selecting signals by wire on the inserters, pumps, and enable/disable options similar to how you can on combinators.

Why?
This allows comparing between two chests to balance inventory in tight spaces without a whole other decider combinator. Can also allow ...

tl;dr
Allow limiting the input ingredient buffer to multiples of the recipe.

06-18-2026, 15-34-02.png

What?

Setting 0 would be only filling the ingredient buffer when it is done crafting. setting to 1 would allow 1 times the amount needed to complete the recipe to fill the buffer. This would ...

tl;dr
Output circuit signal on inserters when idle.

06-18-2026, 15-28-35.png

Why?
This would allow you to stop other inserters from activating until another inserter is done, letting you make prioritized outputs in sequence or otherwise. Ability to remove excess junk or only pull out when ...

tl;dr
Change "trees/rocks only" option in deconstruction planner to two options, 'trees only' and 'rocks only'. They could be activated simultaneously.

Why?
Sometimes you want to get rid of all the rocks but leave the trees for pollution.

Thanks,

Bump. This is still needed. The train station overview information is woefully lacking.

tl;dr
Allow assemblers to change recipe with ingredients still in output and move items in output buffer to input if they're ingredients in the next recipe.

06-18-2026, 15-01-10.png

What?
Currently, you cannot change the recipe of an assembler using circuit signals if it has any buffered ...

tl;dr
A splitter where the output and input sides for each square of the 2x1 splitter are facing opposite directions.
This would help with splitting primarily when coming out of an underground belt, or when two lines heading opposite directions need to be sorted.

Thanks,

tl;dr
Change orientation of logistics items (belts, inserters, pumps, etc.) with circuit signals.

Being able to use circuits to change and control the direction of inserters, belts, pipes, and flip orientation of 2x1's like pumps and splitters would increase the toolkit the player has to solve ...

A light on the corner of assemblers, blinking when crafting, on when full of product, off when short on ingredients.

When making large blueprints or spaghetti, especially with Alt-mode on, it is very difficult to see the assembler animation to tell what is working and what is not. Also if an ...
