I argue for a better MarkDown renderer in the Marketplace. If you choose the github link when publishing a Component and copying of the README.md, the preview shows that your great README.md in GitHub has turned into a distorted text that is difficult to understand. It always takes a lot of painfull adjustments to make it something readable. The result is still far from the representation in GitHub.
I would like to see the same or equivalent renderer used in the Marketplace. The often mediocre displays really detract from the components and the Mendix platform.
