Keyboard shortcuts allow you to change the zoomlevel to accommodate a variety of screen sizes and improve readability. To zoom in use 'F3' on Windows and Command ⌘ '+' on macOS; to zoomout use Shift 'F3' on Windows and Command ⌘ '-' on macOS.
You can also increase the readability of the text by going to the setupscreen and changing Rhyme Genie’s default font size.
