When scrolling the feed with compact mode on, thumbnails are loaded while posts are shown.
Some sort of lazy loading would be awesome here. So thumbnails would get preloaded before you actually scroll down, thus you’d never see the actual loading happen.
Would look and feel much smoother.
It should barely put any strain at all in all honesty. It’s not preloading all thumbnails, but perhaps the next 10-15 or similar.
Most of the time these would be loaded anyway. It’s only the time when you’re finished scrolling it’ll be 10-15 thumbnails that are loaded and not seen.
