The description makes a point to cite the Cybersyn Combinator offering "more slots" for signals relative to Constant Combinators. But... Constant Combinators have functionally infinite slots now. That may not have been the case when this mod was first made, but it is now. They also support signal groups shared among unconnected Combinators and Logistics structures. Am I missing something?

Yeah with 2.0 that part of the description aged like milk, heh.

Used to be that constant combinators were limited to 20 slots, but as you mention now we have logistic sections (up to 100 sections in a combinator, and 1000 signals per section).

I have a branch in progress that adds proper support for all of this. There are some mod APIs missing in Factorio to make it fully functional, but I'm thinking I'll be able to release what I have because it's still an improvement overall.

The things that are currently impossible to implement:

• Moving sections with drag and drop (Forum thread, and also this one)
• Moving signals with drag and drop (See above forum threads)
• Managing logistic section groups (search and delete primarily) (Forum thread)

Got it :) Thanks for the answer, and best of luck including some of those features. I did notice that a lot of the Space Age codebase additions aren't very well exposed to mods.

With v2.4.0, logistic sections are now supported, so you should have access to all the slots you could need now :)
