Thanks for sharing your feedback about the design of an idea conversation in Edit mode. This forum runs on third-party software provided by a company called Khoros, and the fields displayed in your screenshot are included by default. We can certainly ask them about this; would you provide details on what specific fields you might like to see changed or removed, or defined in the UI? Also, did you know that you can share your idea without filling in any of those fields?
@sbeckas Thanks for those suggestions. We're looking into the possibility of removing those fields altogether, but this will entail a project that involves custom coding. For context, here's some documentation from the company that created the form and maintains this platform: SEO-specific title, description, and canonical URL fields for posts
It turns out that someone on our team figured out how to disable those fields. You won't be troubled with them any longer (and nor will we; we weren't using them ourselves). Thanks for raising this issue!
