Formulas

I am using labels to do calculated fields and i need to be able to add logic around that field (label). Can you either add calculated field or allow rules around labels.

For cascading lookups I want the option to filter if a value is selected. Right now in Responsive Designer it's always filter or never filter. I need a conditional filter. Like "Action when no filter applied" "Display all Values"

Please add simple AND and OR functions to formula options. We do have IFELSE and NOT but adding a simple AND and OR function would really help a lot.For example: AND (Input value [,Input value])
