• Add "Render Selection", which replaces a chunk of selected text with a natively rendered view. For example, JSON gets pretty-printed and syntax highlighted. Rendered selections have the option of scrolling horizontally to make navigating logs easier. They are searchable. Over 150 different languages are supported for syntax highlighting. Markdown gets special treatment and displays its rendered format.
