change the padding of the right minimap (both right and left) as it is too close to the text and too close to the border of the screen
it needs, when we scroll down, to go up (it is in the middle of the screen because of the title with a black background on top of the document, but when we scroll down, currently it stays on the middle of the screen, which is weird)
maybe add a background color for it, to make a clear distinction with the content of the document ?
This needs to be done after the issue #34 : it also needs conception so don't hesitate to suggest different things.
