This idea has been developed and deployed to Canvas
At work, I have two wide-screen monitors with resolutions set at 1920x1080. I'm not sure of the reasoning (maybe there is a valid reason that I'm not aware of), but when I view an Assignment (as a student) or a Discussion topic (any role), there is an area of white space that isn't used...as in these examples:
Notice the gray horizontal line across the top extends well beyond the actual content displayed below it for both the Assignments and the Discussions. However, if you look at content in Pages, this white space is actually used:
My suggestion would be to allow both the Assignments and Discussions content pages to utilize the white space along the right side of the page as it does with actual Pages content. (If there are reasons for the white space, I would be interested in knowing why.) The result would potentially create less scrolling for students for longer pages.

This feature was announced inCanvas Beta Release Notes (2017-07-05) and was affected by the New User Tutorial feature, which wasannounced as being enabled by default for all institutions in the 2017-07-15 release.
The Canvas product team ultimately delayed enabling this feature andwas not included inCanvas Production Release Notes (2017-07-15). However, thisideawill still applyfor users whose institutions have enabled the New User Tutorial feature.
The New User Tutorial feature will be enabled by default in a future Canvas release.
