It used to be possible to see full sized pins from boards in sequence without returning to the thumbnails.
The arrows that allow this are now gone, and it is impossible to see pins slideshow style anymore, help center says this was done deliberately as an "experiment"
WHY?
What use are image boards that don't let you look at the images?
It's destroyed my ability to use and enjoy this site and no one can tell me why they would make a crazy change like this.
