Keep it simple. SORT SORT SORT, should be a simple click of the header and not MANUALLY sort. Good grief!
This is how sort works on the workload grids and should be a consistent experience through out the site. Where in the software are you finding you cannot sort by clicking on the header?

All of the Communications Menu Items need sorting and if possible folders. There are still random places where your data is displayed in a table that cannot be sorted.
