Keep in mind that groov View allows you a lot of freedom to create the look and feel you need.
For example, if you want really big navigation buttons, you can build that easily.
Also the platform she will be using most will partly dictate the screen layout… For example, will she be using a phone, a tablet or a PC the most? With groov View you can build the screen to suit both the user and the device.
Here is a great forum thread on the colors and different layouts you can achieve with groov View.
