this may be a bit silly, but I wish the study page

were longer, so I could scroll the writing area to the top of my screen, for more comfortable writing on my Wacom tablet.
I can achieve the same result by resizing the browser to a small window,

but that's less convenient when I use other tabs, which require a bigger window.
So if there could be more space at the bottom of the screen, it would look a bit less nice, but would be more convenient.
