In the Windows Desktop and Web Clients, is there a way to create a custom theme, or to customize the existing themes? I have a hard time reading light text on a dark background, and so having the sidebar be dark on light is hard for me. Even the notes list being black on gray isn't great.

So what I'd like to do is to be able to customize my UI so that the sidebar, notes list, and notes editor are all black text on white backgrounds. Of course, if I've set a folder or note to a specific color, that would still override the basic black-on-white appearance.

Is there a way to do this?
