How do I categorize tasks and events?
The category of a task or event is derived from its description, where the description is split into different parts at the ":" delimiter. The last part corresponds to the short description that is visible in many views. All other parts are used as nested categories.
For Example, the description text
category: subcategory: short descriptionrepresents the following tree
category | |-- subcategory | |-- "short description"
