When looking at the map feedback threads, I'm often confused as to what culture/religion/language belong what group/family. One example is the Polish culture map. It's so granular that I don't always know exactly what culture belongs to Polish, German, Baltic etc.
For this reason, I think it would be a big help, if we get mapmodes for groups and families, not just the individual ones. Additionally, I would also like the grouped categories to be represented in the ledger, so if e.g. I want to compare largest religions (i.e. is christianity the largest religion?), then I don't have to sum up every single little denomination.
