make it all potentially more stable
prevent hot number changing code from running on current loop, which would effectively execute calls out of order
remove testing parts & move strings to xml
remove final variables and rely on instance fields instead
change message that appears when fragment can't scroll to line

make sure 9patch is not downscaled to zero
which results in a crash on ldpi
