I point out three problems related to Descendant Tree Chart:
1) For the excessive number of individuals, not always vertical lines connect all the children. Vertical lines connecting distant people up to 60 lines or so.
2) In case of marriage between cousins, genealogy is repeated according to the first men's line and then according to the female line. Perhaps we must provide for the rule of "not to follow the female offspring when the male spouse has the same surname." I understand that this rule can sometimes be wrong. But perhaps it can be expected to choose between the options.
3) With more than 9-10 generations, IE hangs and fails to complete the construction of the tree, which remains incomplete without the symbols enlarge / collapse. With over 15 generations and 4000 individuals, we plant the PC, perhaps because of the observation in footnote 2). (operating system: e7; 4GB RAM)
Would be very interesting to include in reports of all individuals, this Descendant Tree Chart, also limited to 1-2 generations, in addition to the tree ascending.
Regards.
