So you should make heavy armor require light, power requires modular and Mk2 requires Mk1 armor. The only gap should be between h...

Many objects have the ability to send things about them into the circuit network (e.g. energy percentage of accumulator). It would be great if more machines would allow you to do this like send contents of various machines, output of solar panels, heat in boiler/heat exchanger, performance of steam ...

It would be much better if it just puts one module in the machine, so you can fine-tune modules much faster. You could also add another shortcut (like shif...

It's nothing major, but when I replace the rail signal with a rail chain signal, the attached wire gets cut off. Might be intentional, since the normal rail signal has the ability to close the signal additional to the shared "read signal" mode (which I use). But I only want to read the col...
