So for smooth gauge animations, I mean like the dashboard animations are smoother. The tachometer and speedometer will be more smooth with their movement. The Satsuma mod does this, in fact! I'd like to see that for the official cars. The Custom Shaders Patch for Assetto Corsa also implemented this feature for cars. I don't know, I just figured it's the little things that count. Second of all, I want a custom wheel camera. I know "Relative" already exists but having to manually move it and adjust the FOV every time I switch cars and maps is super annoying. I'd rather it be like the standard interior camera where you can set a specified FOV and then adjust the position of the camera for every car. And then like the interior camera you can also tweak camera movement and horizon lock and stuff.
