(Request) Add intersection, Union, and relative complement filtering mode simultaneously in group filter

Post by yhdelir »

hi, thanks for your great app
could you please Add intersection, Union, and relative complement filtering mode simultaneously in group filter

Union: Combine elements
Intersection: Find common elements
Relative complement: Subtract elements

the intersection(A ∩ B) and Union(A ∪ B) features are already in app that could be used separately but not simultaneously
the relative complement(A − B) is not present in features

for example if we have contact groups A, B, C, D, E, F, G
with the requested feature we would be able to filter groups simultaneously like this:
A ∪ B ∪ C ∩ D ∩ E − F − G

and again another feature request: could you please make this app available in windows OS format with contacts excel input(.xls or .csv file)
thanks in advance
