Request for new features for the sketch component

I have been assigning students their homework allowing them to use a One by Wacom drawing tablet and a Desmos activity with Sketch components.

My personal request is regarding student feedback. I would like the option of sketching over their work, and have any of my teacher annotations saved for the student.
Perhaps with the ability to hide the teacher feedback layer would also be helpful.

My students have requested the option of having an: initialPenSize feature, so all of their slides have the narrow pen.

I believe it would then be possible to allow students to select preferred color and size on slide 1, and copy that over to later slides using CL. But I might need the ability to set initialTool to match the tool of another sketch.
