QuickLook Markdown file previews and icon thumbnails

PreviewMarkdown provides QuickLook file previews and file icon thumbnails for documents created using the popular markdown markup format.

The app provides two app extensions: Previewer and Thumbnailer, which can be viewed and managed in macOS’ System Preferences > Extensions. The app itself is simply a container for these extensions.

You must run the app first to gain these benefits.

PreviewMarkdown supports the following markdown features:

*italics* or _italics_
**bold** or __bold__

Works great

Does exactly what it says, works great on Apple Silicon. My only request would be to allow some configuration of the preview. The single included style certainly gets the job done, but it's far from the most beautiful Markdown rendering.

Developer Response ,

Thanks for the rating. Don't forget you can tweak the preview look using the Preferences panel in the main app. More styling choices are coming too.

Works, gives Markdown Quickviews

Any hope of getting themed display preferences? Similar to e.g. the Typora markdown editor?
