An application walkthrough is used to make the user acquainted about how an application works just by looking at it.
The above walkthrough uses thumbnails of different features of the application.
In the above walkthrough pattern, image occupies the whole length and width of the screen. Buttons and text are used on the image.
In the above image, vertical slider is used to display the walkthrough / tour of the application.
Some applications consolidate the sort and filter options into one screen, typically titled “Refine.” This is the most effort intensive sort pattern, requiring the user to open the sorting drawer, select an option, and then apply the selection (by tapping “refine” in this case).
