Thank you for reaching out! Were you thinking about adding that functionality to our site, or to the mobile app? We've been working to get a back button added to the mobile app, but if you have ideas for the website as well, let me know what you have in mind.
Thanks for letting me know! I think having a more effective back button is one of our most requested features. I will pass your feedback along to our development team, and hopefully they will be working on implementing this tool soon!
