Rated 4 out of 5 stars

Nice addon! But why i can't add any tasks, only events? What I'm doing wrong? When adding the task, it adds in the tasks column, but not in the Gantt view.

This review is for a previous version of the add-on (1.0.0.0b5). 

Make sure that you have the option for "Show Tasks In Calendar" checked - View...Calendar...Current View...Show Tasks in Calendar.

Also make sure that tasks have a start date and due date - otherwise they won't show up on the calendar.
