About the product review: GREAT 🎉

About the tech review: I should use the .prepend method instead of .include so we don’t need to override the entire proposals index controller. It would be better for maintainability if Decidim changes that part of the code in the future… though maybe it’s a bit superficial...
…but I don’t see any problematic breakdown here 👍
Should we not add @moustachu as reviewer ? :s
