Jerboa’s not too bad, as the URL field is the same field the link to your uploaded image ends up overwriting, but I swear I see people making this mistake every fucking day. End up posting just an image when they wanted image + link.
Apologies, as I’m sure there’s proper channels for this, and open source projects tend to not have the best UIs. Just shouting into the void.
The best channel is through the issue tracker, for example github.com/LemmyNet/lemmy-ui. In practice Im not sure how the UI could be changed to make this clearer. Do you have an idea, or an example how another website handles this?
