I don't actually find the notepad useful tbh. I only really use it for the detective career. I don't think it needs to take up space on the toolbar and should be on the phone. But the fishing ones do irritate me a little because it makes no sense for them to pop up in random conversations. Worse still, I get the notification for other Sims who happen to be nearby! So my current Sim will be minding their own business and I get a notification that someone else is discussing fish somewhere 😂. It's never a fishing Sim either. It's a bit of an annoyance to me.
