Visible comments in products

More and more, we want the comments to be visible in the products. At the moment we have to show them one by one.
If it's not possible for them not to appear with the product, then perhaps when you hover over them.
When we create longer invoices where we comment/split/divide the work, it's nice to have an easier overview of what has been included. As of now, it's a bit difficult to see the whole picture for those who create invoices in Gripr.
