the functionality is great but its pretty buggy, Ctrl+z isnt working properly and furthermore the extension froze sometimes, Regardless of that its perfect.

this addon would be great if it wasn't for a little problem, that may or may not be related to linux.

the background cannot be set to a transparent color so it always is blocking the page's content, otherwise this addon has a lot of features while not being cluttered with menus.

does not work on PDFs and has no erase function also a way to type on a page would be good. finally, if it moved with the page when you scrolled it would be good. apart from this it works as you would expect

The drawing itself works great. I find the UI to be very confusing, and there is no eraser tool, you can only clear the whole drawing. Also, if the drawings could scroll along with the page, that would be nice.
