Did you know you can create more Sections within your Reports?
Select Insert | Section from the top level menu.
Here, within the Section Expert, you can create multiple Detail Sections, for instance. This can be very handy when using Suppress and/or Reveal to troubleshoot a report; the idea being to "split" complex or dense areas of the report into separate Sections, making it easier to deal with them as a whole.
I actually find it most helpful to create extra Report Footers, which can sometimes help when dealing with strange subtotals and Groupings. The idea there being that I can have two "sets" of footers, each with their own summaries and fields that can then be Suppressed and/or Revealed, even by a User Parameter.
