Based on the last road map, I am looking forward to seeing what additional types of mechanics are coming.
The power chain is great and I love the inclusion of a transmission and clutch. I am a Dwarf Fortress player and like playing with mechanics. I am hoping some more interaction pieces would be considered for inclusion in future updates:
1. A handcrank: turn nutrition into power. This would allow a seraph to manually provide power to something while still using axels and gears
2. Levers: On/off switch. Allow us to connect a lever to a clutch, and later allow it to be connected to doors or portcullis
3. Button: an on/off pulse. Turn something "on" that is "off" and vice versa.
4. Pressure plate: Allow us to attach with strings (or like in dwarf fortress, connect them using quantum...ness) to a door, trap door, and later perhaps a trap or firing mechanism.
Thanks for your consideration! Let me know if I've overlooked anything. I look forward to this part of the game being fleshed out.
