When viewing the details of a featured artwork under an exhibition, a button is missing that would allow a guest to exit from viewing the artwork and returning to the exhibition page. Currently viewing an artwork detail allows scrolling through all works in the exhibition (great!) but when I want to exit the artwork page I have to use my web browser to go "back" and this brings me to the main exhibition page, in which I have to try to find the specific exhibition I was viewing all over again. I suggest placing an "X" button or a "Exit" button at the upper right corner of an artwork detail page to allow guests to return to the page they were originally viewing. Thanks.
