Thanks Shirley. I appreciate the clarity.
The 'disconnect' from viewing the results (a pedigree containing about 16 people with dates & places) from clicking one icon, clicking 'back' in the browser, re-expanding the ANCESTORS, scrolling back to the find the same ancestor, clicking the other icon, & then reviewing the results (another pedigree grouping) is too much stuff to keep track of.
These are just a example of why a visual guide would be helpful. Your reply was concise but I doubt anyone will be able to find it if searching these forums.
Another example is that there appearing to be multiple 'descendant chart' icons .There is a left and right facing version. But I noticed 1 has the parent along the top to one side of the branching. The other is centered. Would that indicate descendants will be represented differently? Or maybe it's just artistic license in the icon design.
