@SebastianeChen ...
These are both interesting suggestions. I'm not sure if you are aware of this or not, but the Canvas Community site that you are on right now actually has a dedicated space where you can submit your suggestions and ideas to be evaluated. You've posted both of these in the area to ask questions about Canvas. So, what you'll want to do is to submit two separate ideas using the links I'll provide below. And, it's also possible that as you create these ideas, you may find that someone has already posted a similar idea...in which case, it's not necessary to submit again (so as to avoid duplication). Here are the links you need:
Canvas Ideas and Themes - Instructure Community (canvaslms.com)
Click on the blue "View and Submit Ideas" button. Then, on the next screen, click on the blue "Submit an Idea" button...or just navigate to:
Canvas Ideas - Instructure Community (canvaslms.com)
You'll also want to make sure to review the Guides linked under the heading "Ideas and Themes" found on this link:
Instructure Community Guide - Instructure Community (canvaslms.com)
...again, making sure that you are submitting one idea per submission.
I hope this will help in some way!
