Dang, I was not aware uMatrix was not maintained anymore. But it does still its job and has its own usefulness. I like the interface and how everything is layed out easily, where I can allow or deny specific domains or categories back and forth. It shows in a table which domain requests what category (and how many). So this is to me invaluable and a good companion alongside uBlock Origin. I can also just allow only images for a certain domain in example, not just its entirety. Its easy to see and work from this table to me. Like in this screenshot:
