Topology Properties Dialogue Should Alphabetize Feature Classes

[Matt-Huser]

The current dialogue to manage feature classes that contribute to a topology are unorganized or not displayed in a meaningful order by dataset.  This creates inefficiencies when trying to locate the appropriate feature classes. 

My request is that the list is alphabetized by default or by clicking the header you could sort ascending or descending, similar to the header prompts in the attribute table.
