Firstly, you should have posted all of that in a single post, instead of making multiple replies to your own thread.
1. Making a First Person view from a vehicle would require creating the interior for a jeep, as well as detailed models for all of the vehicles. A lot of development for something that is mostly an addon, not changing the gameplay really.
2. One of the mods i played enabled traders to be killable, as well as making the trading post destructible. Discussion about bandits and their usage i would postpone after TFP implements them.
3. Not much sense in adding new animals, especially as it would bring additional management which i think we already have a lot. A fox killing your animals would be more trouble than it's worth, not to mention it would be really small - from my personal taste i rarely run after rabbits, they are too small and run away fast. Also, i have so many feathers i don't know what to do with them, so no incentive on getting even more.
4. You didn't say why you want new zombies. Mods add new zombies that simply don't do anything new or change their textures. No sense for TFP to indulge in that unless they introduce new types of zombies.
5. About weapons, you posted in a separate topic, so i won't reply here about it.
6. Why would you want small scope sights? We already have a 2x, 4x and 8x if i remember, giving a 1.4x or 1.6x is pointless. Poisoned weapons are not for this game, unless you want also freezing, sickness, acid and... nevermind. No sense also to change mods mid fighting, especially on higher tiers of tools/weapons. It still requires for you to use the inventory, i don't see the point for doing it the way you write.
7. Binoculars would be interesting to have. Fragmentation grenade was suggested in another thread (and i agree it's pointless to have it). New armor is the same as with new zombies - why have something that would be similar to what you have? Unless you can wear decorative clothing, this i would applaud. Knee pad protection is surely something that could be done in a mod.
