I like to pick the language of the post because I assume that helps lemmy to sort posts and suggest the correct language to uses.
Every time I have to scroll so a search bar is my suggestion and picking your favorite languages if you are multi lingual.
The favorite languages should be not limited to a limited number.
Huge coincidence but a lot of the requests here are being implemented in the next release. Hope next release will resolve most of the issues brought up in this post/comments.
