Gallery cards are nice, but I wonder if there could be an option to transform the display similar to slideshow in StoryMaps where 3 or 4 display in a row (or like sections in Experience Builder), and then a user uses side arrows to browse the gallery instead of displaying all of them for a given gallery at once.
Then I can add multiple galleries after another based on topic or category, etc. and a user doesn't have to scroll past the entire 8 or 16 cards before getting to the next gallery.
The mobile version could essentially auto display a singular card with the left/right arrows to browse other items.
