GitHub Flavored Markdown viewer plugin for Eclipse
I am glad to share that I have found GitHub Flavored Markdown viewer plugin for Eclipse (GMF Viewer).
It was created by Satyagraha.
There was no update site, but sources compiled without any questions, so I have published GMF Viewer
on Nodeclipse site.
Check for latest version at Marketplace.
I have already started using it.
We will let you know if there are some issues.
Best regards,
Paul Verest
UPDATE:
I have noticed that GFM Viewer (as well as GitHub pages), doesn’t show image referenced as 
when used inside _post folder. Though Markdown HTML Preview does show.
This actually is sright, as _post folder content will get other path when published.
