I was wondering which components I am able to customize within a theme. I don't want to change any moodle core code as I want to preserve the possibility to update.
As an example: Is it possible to create a custom calendar component? Lets say, insert a clock made with javascript. If it's possible, could you please outline the steps required, ie. which files to change etc. Or point me to a link with relevant info?
The reason I'm asking is that the calendar folder apparently is not a "module" (placed inside the /mod folder).
BTW, what's the difference between "modules", "plugins", "blocks", "activities"... ?
Cheers, Ole
