It would be awesome to have for example black paper with grid or have a normal sheet with double or triple grid columns.

A simple partial solution to this would be adding to the page background presets a blank-black and/or a black with blue rules. That would already be a HUGE improvement to the eye strain caused by the display and the battery drain, specially in amoled screens

Users have been suggesting this idea for years, but it seems to fall on deaf ears....even my old, old Linux app Xournal allows you to choose any color from a color palette for page colors. This and syncing to google drive would make the app perfect, since it is already so lag-free and easy to use... I don't understand why they won't implement these 2 suggestions... Silly. I don't use the app any longer based on these two features not being available.

this would be a great addition to the software...

change background color of PDF files 。or
night mode

Other than white

Yes, this would be fantastic... BLACK background, please!

Yes, please! Just started using this app on a Chromebook and I'm in love except for the glaring white background. A sepia option or just the ability to customize background to any color would be fantastic!

Make a black background that allows the app to turn into a make shift blackboard. It is much easier on the eyes and the screen!! Thanks

Please, we need a dark background. All apps have this feature.

+1 for this. Andrew can we get an update on your post from August of 2016?

"Yes, adding the color option for other backgrounds is on our todo list. We didn't want that to block getting the blank page color option out the door, so we just started with that. ;-)"

Black background would be perfect for saving battery and great contrast, while avoiding being exposed to too much light

I really just wanted a pure black background for when I'm taking notes while playing games. But this feature would be a nice extension of that

This is a great idea.

Options for different color backgrounds for notes

The ability to change the standard background (cell, ruler, empty) to any own background or the ability to change the background color.

Возможность менять стандартный фон (клетка, линейка, пустой) на любой собственный фон или возможность менять цвет заднего фона.
