Thank you justarandomgeek and ghoti for making such a simple but effective and satisfying mod! It's not a big one, but it makes controlling circuits much more enjoyable. Just walking up to your control panel and whack your buttons to launch a walking wall of death lasers printed by your circuits etc. And being able to toggle constant combinators is a great feature.
Fits in perfectly with the look of Factorio and looks also enhances the feel.
The only thing I can come up with that is missing for this to be perfect is the ability to fast replace constant combinators and pushbuttons with each other.
