Few features I find useful

Steve, fyi -- integrate it if you like it.

I had most of the module I had envisioned implemented, but after meeting with Fiona today, she doesn't want to look at the slices in this tiny layout in Slicer -- she is used to 3-display PACS viewer configuration, and just use one slice in Slicer to do contouring ... AND it is super cumbersome to handle w/l for the volumes that I need in Fg, so go figure.

I need to regroup and reconsider, or maybe give her a demo with a big screen.
