Then each thumb swipe would only get me through two posts. Are you using an app? I've stuck with jerboa because it puts the community name at the top in a color. Makes it easy to scroll.
Not even in compact view on kbin. For us, thumbnails aren't automatically included in compact and I happen to hate both those things.
Lemmy is big enough that unless I did, there would be no getting away from seeing the same massive identical image over and over forever on all non-image posts, and any original photos would instantly become oases. Everyone would be forced to use those exact settings just to make it half-bearable. Fuck that.
Having just checked how this post looks on the logged-out lemmy site, this suggestion makes a hell of a lot more sense than it did, because this does not look to me like OP thinks it does, I assure you. I was all set to make fun of them and everything.
Really, it's just a want to make the sub icon more visible. Whole thing seems kinda niche, but you could make it happen on a user level. Just not by forcing every post to be an image post, please god
