Hide side bars

Hi! While the app is very useful when used on mobile devices, the side, bottom and top bar do end up occupying screen space which could be used to display the charts instead.

While there is a way to hide the side bar in fullscreen mode and to reduce the size of the bottom bar, they still occupy space. I think it would be very interesting to have a completely fullscreen mode button, that once pressed, would hide every bar on the interface
