I am gathering feedback from our team about the Dashboard, and will post here as I get it. We are still in the development phase, so we do not have a lot of usage yet.
One UI mishap off the top of my head is the navigation menu on the left tends to jump up or down within the frame when the mouse cursor hovers over it, causing lots of mis-clicks.
Likes - Log browser is useful for debugging, Analytics are nice (always nice to have more). Most pages are intuitive.
Frustrations - The small textareas for editing/testing response transforms are difficult to use when they are so close to each other. Perhaps stack them from top-to-bottom instead of left-to-right, or have a separate page/area to work on these and reference them in a dropdown.
