Can I make the preview window bigger, so that I can take a screenshot with clear text?

I want to make a flowchart and paste it in my notes in Evernote. Since evernote doesn't offer Markdown/markmap embeds, I am using screenshots.

Currently the only way is to save your Markdown in a gist and open the gist through "Open URL".

Or you can export it as an HTML and open it in your browser.
