Something I liked about the official app, that no other seemed to have, was the ability to flip through posts, one to the next, without having to return to your feed. If anyone knows of a Lemmy app that can do this, let me know please!

The official reddit app would frequently not load images/posts/comments etc or even sometimes fully stop loading anything at all. I have never had these kind of issues with the third party apps, or much of any other apps of any type for that matter.
