…would be nice to display all the version info upfront in the UI. Ember version, Ember Data, Handlebars, etc. The ability to toggle different ember versions would help in exploring regressions or bug fixes on an existing code snippet.
I have an idea of how we can implement this in the eshtml framework. For example in the {{script}} helper we can set a global flag for each script as Handlebars detects them.
Good suggestion from @eccegordo
