Workspace settings › General › Link previews lists websites that never get a preview: Kemble does not fetch them at all. Workspace settings › Channels › Channel names sets the prefixes Create a channel offers and the guidelines it shows under the name — suggestions, not rules. Channel settings can turn Links off in one channel, and the channel then offers none.
