Interactive Video

Hello I am creating interactive videos (example here: https://h5p.org/node/271712) and I have two questions.

1 - I would like to disable the question summary pages that appears at the end of the video(yello star). Is this possible?

2 -  I am adding question response feedback and i would like to reveal the question feedback when the "Show Solution" options is selected. Right now it only shows what option is correct but i would like it to show both which option is correct AND it's corresponding feedback. Is this possible?

I am getting an error message (occasionally, not sure what triggers it) that says "The from value exceeds the maximum of zero" when I try to add a link or textbox in an interactive video. I can't understand it. There are no other interactions to interfere with what I'm adding... I am mystified..

I have an interactive video on my site with one button to press at the end of the video that takes you to an external URL. I have recently found that by having your plugin activated on my site it slows down the site by 4+ seconds, which is crazy. What can I do to fix this? Or will I just have to not use your plugin?
