UOM class properties dimension table
If you double-click on a UOM class, you will see something like the attached picture. I feel that the "Base Units of Measure" list box should be a table with 2 columns: Base Dimension and Exponent. This would eliminate the ugly ^ and align the exponents.

This would also make configuration of base units faster than the current set up, especially if the cells in the unit column supported intellisense.
