TL;DR

The selector combinator should show the available input and output signals, similar to how the decider combinator shows the input and output signals.

What?

For example, the decider combinator menu:

It shows all the input signals, and shows all the output signals that meet the condition.


However, the selector combinator does not show any input signals, and I think more detrimentally, does not show any output signals:

Perhaps the interface could be similar to this:
(please excuse my terrible MS Paint drawing)

Why?

This addition would be valuable because it would make it easy to quickly see the inputs available to and the outputs produced by the selector combinator. Without being able to see the inputs and outputs, I have to find them by hovering over a power pole, looking at a different (non-selector) combinator, etc. The current interface makes it clear what the selector combinator does (stack size, time, randomize inputs, etc.), but it does not obviously inform the player what its results are.

This information is present in the Constant Combinator's Tooltip. Having it in the Dialog when the Entity is opened would be an improvement, but the information about the input/output is available.

You can also hover over the "Input: Connected to: ###" or the "Output: Connected to: ###" on the top and it will tell you what is in that network.

However +1 for this regardless for consistency and just be better in my opinion.
