Command line options

--scale <num>

sets a scale for graphical objects (staff elements and namebuttons);

the default value [10] is optimized for 1024x768 screens (the main window should fit into a 800x600 screen too); if you use a 640x480 screen you need smaller graphics (too see the whole main window in one screen), for example

klearnnotes2 --scale 7 &

; on the other hand, for screens larger than 1024x768 you may want to use a scale greater than 10 to make notes and buttons easier to look at and click at.
