Technically, there is a 16-tokens frame on the page. You scroll down the rows of 4 (2 on tablet, 1 in smartphone). When you're at the bottom, the signal "lamp" in the menu flares. It means - we're ready to take the new row from the buffer. Buffer is 32 = 16 + 16. Row by row, you take them, and while the upper rows go away, you can scroll up and they appear on page one by one.This is the feature, not the bug. Unlike other programs that clutter the page with hundreds of photos (=making things slow), this one has a floating bubble of fixed size that flows up and down the blockchain.
