I might make a separate suggestion for this, but I've been thinking they could update the inserts section of the mix console to show how the splitter is affecting the inserts. I spent a few minutes editing a picture I got off of google images so I apologize for the quality, but I think it demonstrates a very basic example of what I mean better than I can explain. I'm sure the devs that actually do this for a living would do a much better job haha
Edit: found a better image to use
