Miniaturize a whole logic network into a single entity to save place (similar to factorissimo but for signals).
Mods introducing new content into the game.
Sometimes you want your processor to work with the different configurations on the same data, but not all conditions can be easily implemented via dynamic signals. This lead me to the idea -- what if you create a special virtual signal which can be set, and when the processor becomes packed, all instances of that signal in all settings of all combinators, as well as the processor logo (if template signal is present), are replaced with the selected signal?
I don't know yet if this external signal should be allowed to be dynamic (updating rougly ~/min), or constant only.
Here you have all your processors displaying the ammount of different entities in logistics network.
In addition, each processor has its own image set.
With this feature, all processors would now share the exact same model, and would only vary by the external setting.
