There are already lots of ideas for flow visualizations, but I guess not direct idea for this one? This is so important that I want to make own idea for this one. Give us setting in flows to exclude reloads.
If user makes entry to homepage and refresh the page and after that goes to product page, nowadays flow would look like this:
homepage -> homepage -> product page
But with exclude setting it would be much more useful and readable:
homepage -> product page.
