Hi @m09011,
Apologies for any confusion caused by the "solution" tag. That's the wording the platform the community runs on uses, and it can't be customized. Basically "solved/solution" means your question was answered. I would concur with what @Jeff_F said myself. The apps are primarily used on phones/personal devices where it's unlikely that people would see a dashboard by accident. The web version of Canvas is different in that it's often accessed on screens other people would see. That doesn't mean anyone else would see your screen necessarily, but it's a factor I'm sure Instructure considered and is one of the big reasons grades aren't front and center on a dashboard on web Canvas.
With all that being said, even though this is an answer, I know you may not like the answer given. You can definitely submit this suggestion as an idea for Instructure to consider in web Canvas. We can't guarantee the idea will be selected for development, but you can definitely make your voice heard by creating the idea.
I hope this helps clarify things a bit.
-Chris
