Lemmy UI suggestions

As a new Lemmy user, I have some suggestions to offer regarding the web user interface.

• Collapsible comment threads -- something to click on in a comment to collapse that thread already exists

• Communities sorting -- ability to click headers to sort by Name, Subscribers, Users/month Posts, Comments

• Better community identifers on posts -- Add the community identifier to the top of the post's card to give more immediate context

• Post thumbnails -- Hide the thumbnail instead of displaying a generic image to make better use of space and avoid repeating the same graphic

• Post outline boxes -- In the list of posts, draw some kind of outline box around each post's card for better separation

• Post Sorting -- When sorting by All/Hot, have a setting to control how often the list refreshes to avoid unexpected post shifting while you're reading

Please feel free to add your own suggestions in the comments.
