We did this by creating a set of blank templates (for different business purposes) with clearly delineated sections for filters, "Current Selections", charts, and logos. Sections are delineated with large lightly-colored rectangles that match our company logo's colors.
We saved these templates in a shared folder.
Now, when we create a new QVW, we copy the appropriate template, rename it, and add the script and front-end that we need. We just keep our added controls on 'top' of the section coloring.
It's worked very well to promote consistency in reporting.
