Banners are fuckhuge. Even fitting wide ones like /c/gaming take up most of the page, and then there’s vertical ones like /c/anime which are kind of absurd.
I admit that it’s worse for me because I have to use the site zoomed in and wish the site was more left-aligned, but even at standard zoom, a typical community page will only show 2 actual posts and part of another one. It’s overwhelming.
I appreciate the bit of customizability, but I think they go a bit overboard.
Standardization should be a thing for those, like having either a fixed size or recommended aspect ratios for those.
Same for avatars, there should be a placeholder for when a user or a community doesn’t have one, just make the site looks messy.
