I have many thousand photos in Drive dating back to 2003.

The vertical timeline scroll bar in the photo gallery doesn’t work very well for such a long time span. It doesn’t fit on the screen and is “jerkey.”

Perhaps a simple drop-down to select a year or “paging” year-by-year would be better?

Performance isn’t great when scrolling through large number of photos either. If only one year were displayed per page, perhaps thumbnails for that year would load faster?
