Here is this QOTW: If you could have any new feature in the game what would it be?
For me it would be some sort of husbandry/farming/fishing. Having livestock would be a key element to any survival game. We already have the ability to build amazing bases, so imagine having farm animals and more crops. This has been on my wishlist for 7 Days for Die for so long.
Definitely
Fishing as well, with its own perk, fishing rods of different quality levels, and a fish trap that can passively catch fish or random junk when placed in a river and have mods (similar to other "workstations" like dew collector). There could be several types of fish, some of them good to eat and some irradiated (not the best idea to eat those). This would also lead to the introduction of new meals.
Hunting traps for small animals that can be placed in forests with bait added to them (vegetables or seeds), so that after some time you can collect a rabbit or chicken that spawned inside. And if you do not collect it in time, the animal inside will die and you will only get rotten meat. Maybe there could even be a late-game bear trap that would break a player's leg if stepped on, and if you put meat in it, it could eventually "catch" a bear, a wolf, or even a zombie randomly...
Backpacks. Seriously, make it so the player can find different portable containers that can be equipped in a special slot and add extra rows to the inventory. In the early game this could be a small duffel bag, a regular backpack or even a large hiking or military backpack.
Continuing this idea: more
items that you could find around the city which are
not strictly tied to tiers.
New unique items and weapons. A fire extinguisher? Great - you could use it as a blunt melee weapon, or use it with right-click to put out a burning teammate. A kitchen knife that would be somewhere between a bone knife and a hunting knife in effectiveness. An even better option could be a tactical knife that can be found in military loot. Police baton, maybe even loot-only taser for the intellect skill tree.
Expand
Civilian Clothing by adding things that people actually wear: T-shirts, sweaters, jeans, light pants, overalls, fur coats, winter hats, shorts, etc. Each piece of clothing could have different pros and cons in terms of temperature protection — for example, a T-shirt would help against heat but reduce protection from the cold.
Professional Gear and armor pieces: police and military body armor, riot armor. Firefighter clothing, a construction helmet, electrician gloves, etc.
New traps. Disposable tripwires with explosives, gas pipe fire traps, precast heavy concrete block that eventually fall on enemies, maybe even something similar to different traps from Sons of the Forest? There are plenty of options.
