I get what you’re asking for, and I understand the desire for that level of control. That said, the benefit of this feature doesn’t really feel worth the cost to me.

If it’s just a single note, it won’t stay in your timeline for long anyway—it’ll quickly get pushed out by newer content. But once you add a “hide this specific note” feature, every note would need to be checked against a list of notes you’ve chosen to hide before being shown. Sure, there are ways to optimize this, but the question is: is it really worth it?

That hidden-notes list would also keep growing over time. You might be disciplined and keep it small, but other users probably won’t, and that complexity adds up fast.
