I love Family Echo, partially because of its simplicity compared with other genealogy apps I've tried.
However, I do find myself wishing it was possible to add multiple photos for a person. For example,
-
the person when young
-
middle aged
-
old
-
wedding photo
-
grave
I'm not sure whether Family Echo is still under development, but this could even be a 'pro' feature for which I'd be happy to pay a subscription fee.
