Yay Im loving this game so far, here is some ideas Ive got.A way to make cable management? I mean, they'r so tedious.
Some more ideas:
Electricity:
An alternate switch and more than one input for electric stuff to make more complicated circuits.
Electric AC for hot days, electric heaters for cold (these should require a well insulated house) and electric Ovens to cook food, even electric furnaces if you have enough power.
Also a fridge to keep your food edible (simple stocked foods should rot based on type).
Electric Cars?

I can imagine a long-long-long playtrough where I start as a simple man with some pants made of grass, but after a decent time invested in I can be the cool guy who travels home by his electric car, attach it to a solar charger, go in my well insulated house, drink an ice coffee from my fridge while turrets keep me safe from zeds.
Also charging batteries should be faster than 5W.
Maybe a high level electrician perk to create batteries, solar panels, and the above mentioned stuff.
Comfort level:
Maybe you heal faster or get XP faster for a few hours if you rest in a nice place. This can be achieved by building confy buildings with couches, well insulated walls, nice bright areas with lots of windows, TVs, etc. to encourage "nice" base building instead of practicality.
A little annoying thing for me:
You need a glass jar full of water to create stews, but if you eat it, glass jar is lost. Would be nice to have it back, I think nobody eats a jar with their soup
Also empty cans should be used to store food and prevent rotting.
I mean this game have so much potential, have about 300 hours in it (joined in A16), and I can't wait to finish work and team up with my friends to play today
