Has the location for the my-calendar-custom folder changed? When I upgraded from 2.0.10 to 2.0.12, the custom category icons no longer displayed. I got them to display by moving the my-calendar-custom folder from the plugins folder to the my-calendar folder. In this location, I am concerned that the custom icons will be lost when upgrading to the next my-calendar version. The path for the my-calendar-custom folder shown in the Help page is not clear.
Otherwise, thanks for a great plugin.
