Change event calendar display

Hello, how can I change the display of the event in the calendar app? I need to add the user and must change the colors depending on the category.
Thank you.

Unfortunately you cannot do that with default scriptcase functionality. It’s possible if you hack the code. Not sure if the module of Kevin still applies, but you could look into the following code: http://scriptcase.aducom.com/cms/download.php

Thanks.
