[Notebook]Would it be better if the color of the notes be different from the color of the theme?

When I create a new note, it always take me several seconds to find it.
Maybe it's my monitor's problem, the color of my browser's background seems same to the note.
If the theme of my system is Dark, the color of the note becomes Dark too.

Hello!
After the notes have been adapted to the theme, the interface still has a lot of optimization. This update adds a shadow effect, and you will look better
