As far as I understand play framework views are groovy templates and AFAIK IntelliJ IDEA already supports groovy debugging. Is it simple to add support for debugging .html play framework views? That would be really helpful for some situations, just as you support debugging JSPs. Would it require Play! framework modifications too? If so I think that that would be manageable creating a pull request in play framework github repo. What do you think?
PS: Play! 1.2.x is such a great development framework and if you support it the IntelliJ IDEA integration would be more robust.
