What makes a good UI layout?
The best interfaces are almost invisible to the user. They avoid unnecessary elements and are clear in the language they use on labels and in messaging. Create consistency and use common UI elements. By using common elements in your UI, users feel more comfortable and are able to get things done more quickly.
