I just finished creating and posting to Youtube a short video demonstrating the new OMEGAMON z/OS V5.1 enhanced 3270 user interface. The video is just a short (less than 10 minutes) demo of how the new UI works, and how you can easily navigate using the tool. You'll be able to see how you can easily navigate and drill down, using the new 3270 UI, to solve common z/OS problems.
Here's a link to the video. Feel free to take a look:
