Option to change the color of the backround lines
I would like to have the option, that I can change the backround lines from blue to black or grey.
I use this app in my university, so i have many notes which i have to print out. I print my notes in colour, because I mark many things with colour. The problem is, that the backround lines are blue. So I have to change the blue ink of my printer double in the time I have to change red or yellow once. And I can only buy the blue ink in combination of red and yellow.
