MarkdownGlance previews Markdown in the same Sublime Text window.

Open a Markdown file and run "MarkdownGlance: Open Preview to the Side".
Mermaid and LaTeX math rendering are off by default; enabling either sends
diagram or formula source to the configured server. Remote images are fetched under size and timeout
limits. Details: https://github.com/pandadolphin/MarkdownGlance#readme
