Category titles

Can this plugin act as a ‘table of contents’ widget in a sidebar that will list posts by category (not the categories names themselves, but rather all posts within a specific category). So, for example, if I have a page with “A” content, I want to have a custom sidebar listing all related post titles (links) within the “A” category. And similarly, another page with “B” content, want to have a custom sidebar listing all related post titles (links) within the “B” category. I’m using Quince theme so custom sidebars are a snap, and though it’s fairly easy to find a “category title” widget option, not with the ability to list specific categories themselves…
