We just implemented a chat slider across our library's website <https://library.ubalt.edu>, set to open automatically 10 seconds after page load. Although the slider seems to be increasing our interactions with users, I am worried about a negative affect to usability or accessibility. NNG clearly says <https://www.nngroup.com/articles/popups/>that pop-ups are generally bad, but the slider isn't quite a pop-up. Anybody have some authoritative info on the usability and accessibility of chat sliders? Regards, Kyle
