I was using Good Notes for a while, it was great. However, I can't stand the blue color of the ribbon in the UI any more (it's the same for me as with the OneNote, I can't stand their purple color). The white and blue UI in the reading mode is alright, however in the writing mode it becomes very annoying. Could you add an option in the settings to change the color scheme to white and gray (or some smooth black), at least make an option to preserve the reading mode scheme all the time even in the editing mode. Also, as we are talking UI, could you optimize the tool panel, as well, with a floating movable circle, expanding it to an oval with the tool icons.
