It's limited by height, so I guess rotating your desktop is one way to handle that
. Right now it's not possible to use large fonts on a smaller screen, since allowing it would mean there's no way to move the window, and the tools etc will appear off the screen and become partially or entirely inaccessible.
Since you mention it, this could be addressed as part of a future update that allows for a more dynamic UI, so the tools don't have to all appear in one vertical block on the left, and could be spread out or optional.
