Do you use Adobe Bridge? I do all the time and couldn't image working in Photoshop without it.
I don't, however, use Mini Bridge as much, but this video showed me some tips that I wasn't aware of and I'll be sure to use it much more now! The video is using CS6. I only have CS5 so there were some features that I don't have, but I still found it very useful.
