I also hate the 1-line summary in the built-in widget.

I have two proposals. Check if you find any of then useful:

Proposal 1:
I currently use the widget with 9 lines, I can accept up to 3 lines at the bottom of the widget allocated to tasks. If there are more than 3 pending tasks, then 2 are show, 1 line is used to say that there are more pending tasks not being shown (similar to the built-in widget) and the 6 top lines are used to show the normal events. if there are less than 3 pending tasks, then only the needed lines are used for tasks and all the other lines at the top (7 or more) are used for events.

The number of allowed lines (3 in my case) could be configurable.

Proposal 2:
Mix them between the events as they are mixed in the calendar-ui (weekly and monthly vuew). You can differentiate tasks from events using a different icon (for instance, the same icon used by the calendar-ui).


Hope this help.
