Yes! I'm totally with you here... That could give you lots of new options. Also, the AND relays could be really great... Not to add two powersources to the grid, because that is difficult to code, so I don't see it happening ever. It's more so I can have something turn on with, for example motion sensor, but also a switch for constant power...
I believe Prime is in charge of the electrical stuff... In his latest QA session, he talked about being pressured a little, to get powered doors and powered drawbridges done for A17. But he had so much stuff left to do and fix, that even this might not make it for A17.
So! Let's cross our fingers, and remember to give many many hints during A18 development. So maybe the electrical system can get some love...
I just find it immensely fun to build with!
