This is a feature that should be considered for future versions.
From a design standpoint it is a little limiting to not have the ability to control that aspect of the calendar. I have certain colors I am using in my design and would like the calendar to match.
I would have also liked the ability to move the navigation arrows to the left and right of the month and year, but I understand the importance of encrypting the code.
With that being said, overall I am very impressed with the app, and I will still purchase a license. I have not seen any other calendars on the market that are built well! (and the license fee is quite affordable.) I will keep my fingers crossed that in the next version we will have the ability to control the colors of the text.
