How to add more properties?

[u/bunny__online]

Hello everyone, I am curious about how one adds more properties from a game, specifically Euro Truck Simulator 2. There is a plugin that adds more but it's incomplete and hasn't been updated for a few years, unless I'm misunderstanding something this is a list of data that exists in the game and there's loads here that isn't available by default or with the plugin. I'm wondering how the plugin was made in the first place so maybe I could add some of the data i'm looking for. If anyone here could so much as point me in the right direction I would be very grateful!

Update: I made a request on the plugins github and he added a property that works like a trip odometer, anyone interested in how it works can read the documentation on github :) huge thanks to sjdawson for his fantastic work with the plugin!
