I don’t know if I’m just missing something, but is it possible to crop the full image previews to just take up a variable amount of height in the feed (like boost)? I’d prefer my images not take up more than 2/3rds of my full screen height so I can always see the post title.
If I understood the request correctly, you should be able to do it by tapping on the three dots on the bottom right of the screen -> Settings -> Posts feed -> Post appearance.
