I haven't done a full Cosmere reread, but I like to reread the previous books in each series before a new one comes out. There's so much forshadowing that you pick up on in rereads!
The part I don't understand is why it's important to hit the "replacement level". Wouldn't it be better for the planet if there were fewer people living on it and competing for resources?
I strongly dislike in-app browsers. I've found the "open in browser" button, but I would much prefer a setting toggle to bypass the in-app entirely
