What is the best – or optimal – way to present and document long screens? This is especially a problem with long mobile screens. For example how do you present the bottom menus and other sticky elements? I personally hate to see designs where the bottom menu is at bottom of a long screen. It doesn't represent the reality. Please share how do you do it and let's try to set a standard for this. :)
We mainly use invision, so we can walk through the entire mockup inside an iframe. The tool allows you to make sticky headers and footers by selecting areas of the mockup. Its free to try!
