I see you didn't mention any problems taping chapter titles
I don't notice chapter titles as much. Like it was said before, the chapter titles are longer, so it might be easier to select them. The more likely thing is that I only select a chapter title once, when I'm about to read something, so if I misclick once it's less of a big deal. The read icon I notice more, because I'm more likely to select it multiple times when I've forgotten to mark something as reading before I begin, and have to go through and select all the chapters I read.
Going down the list and having to click them so many times is what made me realise that.
