... in the same tab as number and equations) could be used to represent the red or green circuit output?

I've attached an example for the input of a splitter where it would be easier if the red and green wires could be attached directly to the splitter, using the red and green signal icons to represent ...

... rod and collector: charge

also there are creative items, that should be cofigureable by wire signals:
- infinity chest: see resquester/buffer chest
- lane splitter: see splitter
- heat interface: set temp & other settings
- electric interface: set sliders and modes
- bottomless chest: on/off

... of inserter outputs


What?
Using circuit conditions the player should be able to switch the output lanes of an inserter similar to how splitter circuit conditions work

Why?
it would allow the player to feed two items on one belt via a single box in ...

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.

Inserters picking up from a splitter only ever take from the output side of it, that I know, it is consistent.
However, this behavior is not very obvious and it rarely actually matters, but when it does, the pickup indicator can be very misleading and lead to dysfunctional deigns that will teach you ...

yeah, that sounds about right! Splitter filter was only 'quality X and above' or 'item of specific quality/any quality' last I played factorio.
to do 'quality X and above for specific item', you could stack two splitters one right after the other, but like, that feels jank.. (though taking a look ...

For loading splitters/belts from mining drills, there is a workaround with circuit conditions:
https://www.reddit.com/r/factorio/comments/1r9dy7v/full_belt_from_mining_drills

Add a belt before the splitter (which is being loaded by the miner) and connect it to the miner. Set the belt to read all ...

... and why. It is possible to recycle only the excess above 55 per minute instead of almost everything with a few extra combinators blocking a splitter in the top right corner, i was too lazy to add.

5) The system must be reconfigurable to any other end ...

Swap splitter priority ui top and bottom

What?
Switch the position of the input and output splitter priorities.

Why?
If a splitter faces north, the input is in the bottom, and the UI input is in the top. And the output on top, UI on bottom. But, the ...

TL;DR
Allow the "No Item" (gray 🚫) signal that appears in circuit-controlled splitters to be selected from the GUI when setting filters on splitters.


What?
When splitters got circuit control a few months ago, this introduced a new signal, "No Item." The only place this appears normally is in the ...

Use case for soft filters:

Multiple parallel sushi belts, with one exit for red circuits.

At present, you need separate filtered splitters for each sushi lane, merging the red filtered outputs after the exit.

With soft filters, each lane can send red circuits towards the exit without blocking other ...

If I understood right, it could easily be achieved with combinations of splitters.
It's general rule of thumb not to add such things, to keep core idea that anything from basic ones and zeroes, even if you had to come up with some 'trick' that has become basic themselves. That's why they don't add ...

... a design that used a deconstruction planner as the NO EXIT THIS LANE marker, the big red square is a nice visual indicator that that lane of the splitter output is blocked. I do agree that it would be nice if that was a setting rather than a workaround, especially if it was configurable via circuits.

... If you relabel a quality part, and merge it into your normal-quality production chain, your job is done. It can make its way through any filter splitters, filter inserters, logistic bot systems, trains, space platforms, circuit conditions, AND assemblers/chemplants/EM plants, exactly as a normal ...

Maybe it could be additional Mode parameter like that you need to pass to splitter rather than adding this to each signal

TL;DR
Add circuit control to lane splitter and fast/express/turbo lane splitter

What?
Recently splitter have gotten circuit control logic. This feature was not added to the lane splitter at the same time.
The base game also only defines lane splitters for yellow belts. The other belt speeds are ...

... each potential output require a dedicated slot whereas for items it can be the same inserter that output them on a belt filtered later with splitter, for fluid if you have static setup where the recycler will have always the same input it's not so complicated, but as soon as you try to have a ...

TL;DR
Allow the quality range setting seen on inserter and splitter filters to be used in circuit control GUIs, like decider and arithmetic combinators, enable/disable circuit settings, etc.


What?
I would like to use the :any-quality:, >, <, =, >=, <=, ~= quality evaluators inside of signal ...
