A widget for posts from single category?

Is there a sidebar widget that would add all posts from a single category that you designate?

I see a widget for recent posts, monthly posts, categories, etc.

For example, I want a list of posts (in a single category) in the sidebar. If/when I change the title or delete a post, it is updated in the sidebar as well.

Right now I just added a text widget and manually added links to each post, but if I update things I then need to update them in the widget too.
Thanks!
