Sketch Plugin Idea

Have you ever had your list of to do's in a text layer, on your canvas, in Sketch?

I certainly have. I always end up with notes floating around, zooming to be able to read them, and having to move them around constantly.

I've had this idea for a while. A simple plugin to add notes and tasks to artboards in Sketch.
Heres a mockup I made today.

Now... Is this something you would use?
What would you like to add/change/remove?
