Rounds 2 and After - Prototype Pictures
The table below shows the changes we made to the prototype based on the user feedback in Round 2.
Changes | Round 2 | After Round 2 |

Changed the caption and the icon of the Grid tab to Sell Power and a $ sign, so users without smart grid knowledge can still easily understand it.

Renamed the Device List to Sort-able Device List. Hopefully this change makes the caption more descriptive to the tab’s function, and gives users a stronger hint on what the page will do. Also added a Select All and a Clear All checkboxes to make checking/unchecking the device checkboxes more efficient.

Added a warning dialog if user leaves the Device Settings page without clicking the Save Settings button – we have seen users forgot to do so. No dialog will show up if user has clicked the Save Settings button.
