Agreed. Just some random thoughts

- I'd add some indication of how long the tour is. Felt like I clicked for a while. Maybe I'm just impatient.

- Highlight the input that the tour popup is currently referencing in some way (eg add blue focus border)

- All of your inputs have explanatory text below them, and no labels. They also have no spacing to show what goes with what. You should add labels above the inputs, and put the explanatory text in a tooltip

- You have a breadcrumb kind of display on the top right side. Usually that's on the top left. I also expected it to be interactive since it is styled in blue, like a link

- Can you put the search results in an iframe or something, keeping the user on the same page? Opening a new tab was unexpected.
