Canvas Question: Pinterest Widgets

Don't ask me why, but the only way you can display a Pinterest Board is to create your own HTML file, insert the javascript, and then upload that file. The javascript in the file works, but the same javascript in a Canvas page will not work? Perhaps a Canvas guru can enlighten me about that!

This link takes you to the file so can see what I mean: pinterest.html.

FWIW you can also see that the Pinterest Board renders if it is inserted into a Blogger blog post which is embedded via iframe.

But when I put the exact same content of the HTML file into a Canvas page, the Pinterest Board does not display. You can see the result here: Pinterest test page.

Canvas Question: content display area

Is there anything I can do about the top of the screen in the Pages section of a Canvas course where the big blue "all pages" link sits now? It would be great if users could at least pop that space closed the way they can pop the left-hand nav bar closed.

Do the numbers: if the user doesn't learn to suppress the left nav bar (which they have to do with EVERY NEW PAGE; it is not persistent), then that means out of 800x1200 visible pixels, only 550x800 pixels are my content. So, that is 440K pixels out of 960K pixels: I am getting to use less than half of the visible screen. Ouch.

My actual content is in the red box below:
