I'm not allowed to talk about the majority of the tools that I built and worked on at IMN, but I'll talk about things that are public.
The "Get URLs from Search Results Plugin Tool" located here is a Greasemonkey script I created a long time back. I also created the page for it, including the directions and screenshot.
The "On Page Optimizer" tool here is something that I did maintenance and upgrades on.
In the video below (at the 13:12 mark), you can see founder and CEO discussing another tool that I built. While he never created a video highlighting its use, its very similar to the tool he shows in the video, except, as he says, it takes in lists of links from third party backlink sources, and compares those lists to the list of backlinks provided in Google Webmaster Tools. Lots of processing to determine mutual exclusion/inclusion between the lists, and AJAX and jQuery (and checkboxes and dropdowns) on the frontend to generate lists of links to be exported.
