One thing I keep hoping Applix will do is to putting hierarchy indenting into the cube viewer. It should also be automatic within dynamic slices.
If you look at xlcubed or Temtec (which Applix just purchased) they always show the hierarchy as indented when you drill down on consolidations.
The InSpreadsheetBrowser has been doing it for years and I'm sure every user would like to see it in the cube browser and when they slice a view out to excel
