Would love to see an improved variable change log incorporated within the Report Suites area of Admin Console (Conversion Variables, Success Events, Processing Rule, Traffic Variables, etc). I could see this as an additional expanded menu that shows changes for that specific variable and the date. This would help with quickly debugging issues and keeping a record of changing that can have a large impact on your data.
The Admin Tools Log is not exactly what I want to be sifting through when I am double checking a change seen in a particlar variable and need to get a better understanding of potential changes on this variable's settings.
