[Feature Request]: splines to have a more defined curve at sharp angles

### Is there an existing issue for this?

- [x] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?


When there's a connection that is at a sharp angle, it goes behind the node in such a way that it's difficult to tell that it's even connected. This is a request to make that a bit more defined so it's easier to see. In the picture above, the **second** input (labeled `specific`) is what I'm talking about. You can _barely_ see the connected line.
