all content types

I lost an important project due to not able to change background color of h5p content.I completed the whole project but due to not able to change the background color if content client rejected to accept it and my work of more than a month was of no use. h5p contents should have a option to change the background color or make it transparent so that the user can make the content presentable.Kindly update h5p and add this option else its contents are of no use.I am looking for the update ASAP. 

Hi! I'm using H5P on a WordPress site, and I wonder if there's a way for users to view past saved submissions? I'm thinking in the context of giving a reflective question to come back to later, or reviewing a question done yesterday kind of thing. 

I know that I can see some statistics on my back-end, but I'm looking for a way for users to go back to past work on the page. It's OK if they have to log in or something (or tie into another plugin?) to do so. 

Hi, now google uses Practice problems structured data. Do H5P provide such information to google? if not, i could be a great adition.
