Hi Fab - welcome on board, glad you like the site.
The Recently Viwed Routes section on the home page will always show the routes you last looked at, so any routes you are no longer interested in will fall off the bottom of the list automatically as you view other routes.
i'm a new user just joined and I really appreciate the website.
I would clean up the "RECENTLY VIEWED ROUTES" session, i searched in the forum but I didn't find any answer.
Apologise if this was alrady asked and i wasn't able to find it out .
