Hi @KirstenThomson ...
Thanks for posting your comments here. Unfortunately, this isn't the exact place to submit your ideas for improvements to Canvas. Fortunately, though, I can point you to the correct areas to do this. However, do know that the entire feature idea process is undergoing some changes these days, but you can still submit your ideas so that they can be evaluated at a later time. While I don't know exactly what that new process will look like, I'm hopeful that it will be beneficial for everyone. For starters, you'll want to read through this blog post:
Turning Your Feedback into Better Prioritization and Release Processes: Our Path Forward
Then, you'll want to review these Guides:
I hope these links will be helpful for you. You may find that an existing idea already exists...in which case, you do not need to submit a new idea (to avoid duplication). But, if you do not find an idea that is similar to yours, go ahead and submit your idea. Good luck!
