Excel Slicer Control
Excel 2010 / 2013 Addin for Slicer Control Management
Excel Slicers are a great way to do data Mining and works great as designed. One of the features that Microsoft forgot to add in was the ability to rename a Slicer.

While this is not a great pain in normal circumstances, when you switch to using OLAP cubes (Powerpivot) and need to write cube formulas- You REALLY miss this one.
