I'm new to H5P but am starting work on a project that will use it extensively. I am working on a sample "chapter" and I used a name for an interactive book file that I would like to change. However, I haven't been able to figure out how to do so. Can anyone help me with this? Am attaching a screenshot below. 

Thanks! 

I can't upload my h5p files to my moodle lms. It says:

Missing required library H5P.MultiplayerClient 1.0

Missing required library H5P.Chase 1.0

Hi everyone,
I'm working on an interactive video, it's HD720. I'm inserting a Drag and Drop activity, a background image and setting it's size to 1280x720 (image actual size is the same), but when I visualize it the image is too small, I can barely read the informations.
Is there a limit to this background image size? 

Oh, and what is the criteria to position this window on the left or the right side of the screen?

Thanks to you all.
