The new date slicer is awesome, but it would be so nice if you could set a dynamic date selection instead of a static. With a static filter the user will always have to set the dates before the saved...
Amuses me that BI reports are consistently built with From and To date prompts even when the report is titled something like "xxx Monthly Report". 99.9% of the time users always put in the first of the month to the last day of the month, and run the report at 9am on the ?th day of the subsequent month. Relative date filters make life a lot easier for everyone. I would add previous periods to the list of options.
