Plugin for Category Sidebar, limited to current category

Hi,

This isn’t a WPMUDEV support question, as such, but just out there to the advanced WordPress guys to see if there is something that meets my needs. (there must be)

The standard WordPress recent posts applies across a whole site.

What I am looking to do is to have a sidebar that is only displaying recent posts relevant to the current category.

So on category archive or a single post only display the relevant recent posts for the same category.

Must be a good plugin for this out there!
