The ability to note recurring tasks
Some tasks occur daily, others every other day, others weekly or biweekly, and others rotate on and 18 day cycle. These tasks are catch as catch can, depending on the day's appointments, rather than at a specific time. For example, every Thursday I need to request golf tee-times the next week. The time of day I do it varies from 7am to 8pm. It would be cool to have a sub-window that could be called up or just exist in the background until I have a moment to remind myself of pending tasks.
