Dark Mode looks good - better than any of Dark Reader's modes for the Canvas site.

The assignment list is going to be VERY useful for me, wow. Nice one. The gradients are a nice touch too.

I'm not sure how the link preview feature works - I tried a few different kinds of pages with links without ever seeing a "show link" button appear. Maybe another extension of mine is interfering or this feature is outdated.

I can see the appeal of the GPA calculator but it's not for me. (it is by semester/quarter) My ideal Canvas extension would have a button on the grades page, to tell you which assignments you must do well on to pass the class, taking into account the weight of different assignment groups and assignments that haven't been graded yet. But that's just an ideal.

To me this extension is worth it for the assignment list alone. I have poor internet speeds where I live, so it is a chore to load Canvas pages just to check due dates.
