@Anhalter42 I spend some time going through the calendar module code, i can read it fairly well, for the syntax i dont understand there is always google. After review, I see why there are no separate fetchInterval’s for each calendar. Each calendar’s events are added to an array, then sorted together also the dom (html table) is created from scratch on each interval. Without a tremendous restructuring of code, setting up separate interval timers, persisting the ical events array, etc. the value to adding this is limited.
Your comments help me immensely, thank you. I reviewed the template module, i’l start playing with that and do a Hello World module exercise when i return home at the end of the month.
