I developed a small tool to help visualize, export, and analyze stories in our projects. It is meeting several of my needs and I thought I would share it with others. I have open sourced it at GitHub - sappling/rallyx.
This lets you export your Initiative / Feature / Story tree into a Mind Map, export to MS Excel, or export to MS Word. It also can run some simple error checks for problems that I was frequently encountering (like stories under a feature that had no release assigned).
This was made to just address some of my needs, but hopefully will be useful to someone else.
