Recurring Tasks
Chaos Control lets you add repetitive tasks for those actions that you perform regularly.
For example:
"Go for a morning run" - every day

"Do the grocery shopping" - every Saturday

"Work on the company's development strategy" - every 2 weeks

"Pay for hosting services" - once a month

"Meet with partners and discuss the current state of the project" - every Monday and Thursday

and so on.
Flexible recurring options let you set up almost any kind of repetition. You can do that in the standard task edit dialog:
In this example the task will be displayed every Tuesday and Friday on your Daily Plan.
