This might help: Make a backup of Runtime/UI/parmDialPrefs.xml. Then open it in a text editor an search for the lines that have name="name" and name="value". In these lines, find the textSize attribute and change the number after it (default is 12) to something bigger - try 16 for a start. In a similar way, you can change the dial sizes by changing the bottom and rect.bottom values of dialBackground, dial and dialGradient.
