A few things that I think could improve galactic life and that I would look forward to: Signals: Read out of device queues (filled/not filled) / Goal: Switch off the constructor / food fabicator etc. when finished. Brightness sensor: Sensor which detects the brightness and switches at a threshold / Goal: Construction of lighting systems which only light up at night or fog. Motion detector: Option to detect only NPCs. Extension to the current "also detect NPCs" / Goal: Only switch in the presence of NPCs and not of players. Block copy: The block you are looking at, will get in form and color/texture by keystroke, if the basic material is in inventory / Goal: Make building or rebuilding faster, must not always be tried, which form, color or texture.
