I know there are several netflow resource panes and all of them can be clicked on and drilled down to get more info.
I think by far the most important resource is Top X Conversations. I know the way we use it, that is the first place we look for netflow related info.
I think with some tweaking it can be almost a dashboard unto itself giving you in one glance alot of info. For example adding the ports used would be helpful. Another thing would be to list the application if the ports matched one or which IP address Group it may be associated with.
Here is an example of what I mean, here are the field headers
