I think I will probably remove the blue theme and set the black theme by default instead.
This is really difficult in Android to manage different themes. This can take me a lot of time to add another one since I have to rework all the colors management.
And many users are requesting me a new theme with high contrasts for the OLED displays (in order to save the battery)
So, if ever nobody use the blue theme, this would be the possibility to replace this one by the high contrast one.
