[Feature request] Left-handed layout option on the tablet

[saxc]

I use the app as a left-handed person on my smartphone and tablet (landscape mode). In landscape mode, the sidebar cannot be hidden, which means that i have to reach across part of the screen from the left to be able to scroll. I would find a layout option helpful that allows the sidebar to be toggled from the hamburger menu in landscape mode as is currently possible in portrait mode.
