TLDR
The Each virtual signal is confusing. I think it can be made clearer by making it primarily a configuration option, and reusing the new BP Parameter Icons.Why?
As seen in reports such as viewtopic.php?f=23&t=119967&p=633679, Each has some confusing edge cases.It even confuses itself, with no need for Any/Everything to get involved. See the below with what appear to be logically identical conditions, but they aren't due to the R/G selector.
Proposal
This can be broken down into two parts.(1) Each changes the behavior of the Decider Combinator so much that it should be moved to a configuration option.
(2) The Each Virtual Signal should be replaced with a blueprint parameter signal. By reusing the UI language introduced by parametrized blueprints, it indicates that the signal is being replaced during operation.
In the Mockup below, you can see that it is possible to control both which Network's Signals will be considered for iteration, and which Network's value will be used for each condition and output. This is an improvement over the above examples where otherwise irrelevant conditions are added to expand the list of iterated signals.
P.S. This Mockup is intended for visualization only. I have done my best with the logic, but it was built in GIMP from several different screenshots, so there may be mistakes.
