I have to say this is a good and solid new release.
However I believe on the “Add Rule Set” we need to have a ability to filter by RSID, lets say your working with a large organization and they have different RSID defined based on locations like USA, UK, France, DK. They all have different marketing teams with different set of goals in mind but all use the same eVar number. By having some sort of RSID filter we can easily look for that global eVar by filtering the RSID, this can reduce errors and mistakes. Having a large list is not a good option.
