I would like a info panel that show me relevant information about the file. For me that information would be: Paper size (not including bleed) in milimeters, Color profile, bleed size, Ink limit, Spot colors, low-res image warning, fonts etc. I use Acrobat to check ads and I think a single info-panel would be great. If there is problems with the file, I can dig deeper with pre-flight, but in most cases I only need to know the basic information about the file. The Properties panel under the file menu is better than nothing, but it is too limited and shows the pagesize including the bleed margins.
