Option to hide non-task content

When completing tasks, there’s already the toggle to show or hide completed ones, which is great. But it would also be useful to have the ability to hide other types of content (like notes or sections) that aren’t tasks.

Maybe we could right-click and select “Hide” on any item, and then have an “Unhide all” option in the three-dot menu. This would help keep pages cleaner and more focused when working on active tasks.
