Just some ideas

Ideas

Having an option if you don't have a weapon at all, to shove a zombie knocking them into prone and allowing some time to escape.

Able to use different survivor profiles, so that you can play without friends on a different character

Allowing an option to remove the debug monitor

Adding a character storage unit or lock box that allows you to put stuff in and saves even after server reset with a coded password so others can't steal your loot. But are only able to get in it by using certain tools to get inside it. Which transfers with your character when you switch to a different server at the given location you left it at, allowing you to move it again if needed.

Making a fort or barricades that zombies can't pass through but can destroy if not repaired.

flare guns to light up an area in the distance

PDA that track points of interest or notes, and allows player with right items to set up sensors.

New player models or customization

Allowing us to repair a train to use for transportation

That would be a good one. Kicking in the head option.
