Love the integration of Gravity and the Members plugin. I was able to create a custom role for a client to just retrieve Form entries.
A suggestion though. It'd be good if interface elements they cannot access were hidden.
For instance on the dashboard widget, the View All Form button should be hidden if they can't access it. Likewise, when viewing Entries, there are buttons in the toolbar above for Form Editor, Form Settings, Notifications & Preview — all of which they can't access, but they can see.
If they click on them they get the proper "You do not have sufficient permissions" message, but from an interface and usability perspective, it'd be better if they didn't have them to click on in the first place.
Thanks,
Michael
