Is your feature request related to a problem? Please describe.
I'd like to be able to control the javascript execution flow more granularly and I feel like being able to sleep and/or wait on elements might be useful. Screenshots seem to show that items are still loading when it is taken which result in an incorrect page being scraped

Describe the solution you'd like/Describe the use-case and give concrete real-world examples
Maybe more examples, or at least a couple of more complex ones? Logging in, then clicking on elements in the next page etc? More clarity on how to wait for a new page to be loaded or just for a given number of seconds.

Thank you
