It will be nice, if I can see difference between sibblings in modern tree. For example, my ancestor had 9 chldren, and 5 of them died as child. Year was 1733, I doubt I will get any photo of 65 percent of persons in my tree. It is nice to have in Modern tree pink silhouette of woman and blue of man. But it will be better and nicer when the tree do the math with date of death minus date of birth and you get number 0-90. So children are 0-15.
When tree do the math and number will be between 0-15, it will change the pink or blue silhouette to slightly lighter pink silhouette of girl with 2 hairtail or blue silhouette of boy.
Or children dead between 0-15 years of age will have LIGHTER pink silhouette of girl or blue silhouette of boy.
