Simple thing of a mod, this. If you hold alt when scrolling your mousewheel, it zooms your map instead. Not holding alt does what the wheel normally does (under usual bindings) and alters the camera.
I threw this together as I was tired of having to move my cursor over the minimap every time I needed more precision to spot nodes. This is just a QoL thing that made my game experience better. So I'm sharing it so that it may do the same for you.
