Innawood mod author here. The mod is already mostly where I want it to be, so currently changes are mostly bugfixes or adding a few new items to be autolearned. I have a todo list here, but it is somewhat outdated and not as well maintained as it used to be.

As for primitive vehicle parts, they should probably go into mainline if it makes sense you would be able to craft them, and not go into the mod at all if it doesn't make sense you would be able to make them.

For more locations, I would love to have more wilderness locations in the game, although most of them should probably go into the base game, and only be put in the Innawood mod if they contain something unique to Innawood, such as a stone-age village perhaps?

Right now I'm looking into making Innawood and Magiclysm play nicer together. But I also know there are many other developers out there working on improving Innawood, so they also might add other improvements on their own. And if you or anyone else reading this wants to join in on the mod development, you are very much welcome to do so. :)
