I would greatly benefit from being able to adjust the font size of the date number. I utilize the monthly calendar exclusively, viewing all 12 months simultaneously.
I use YG on a vertically oriented high res 50" screen on a wall in my office 8' away from my desk. The 50" screen is dedicated to YG calendar use only. Throughout the day, I look at the calendar countless times for endless reasons, most of which do not require entering an event. The date is incredibly hard to see.
Also, I would like the ability to hide the menu but still have access.... much like the hidden windows task bar. The left menu takes up valuable screen space in a vertically oriented 12 month calendar view.
