I'm using subforms for a few of my forms. Some of the records have many subform records, ie 50+ children.
I have views that display the form and subform results. The views currently display 1 subform entry per line. For entries with multiple subforms, it is very hard to read.
My suggestion is to have subform records either comma delimited or per lined as an option. It will make it easier to read rows with multiple subform rows.
