Core Concepts
Core Concepts
Section titled “Core Concepts”YYNote has three core data types: Todo, Sticky Note, Schedule (+ Countdown as a special todo type). Understanding the differences is fundamental to using YYNote correctly.
A pure task item with no time span.
- Appears only in the Todo List
- Can set a reminder time
- Can set repeat rules
- Can set a target date (becomes a countdown)
- After completion, appears in the “Completed” list; does not auto-disappear, can be restored from the completed list
Typical uses: Call a client tomorrow, submit a report by Friday, buy milk
State machine: 0 = Pending, 1 = Done, 2 = Deleted (todos have no “archived” state)
Sticky Note
Section titled “Sticky Note”A simple text memo with no emphasis on time.
- Appears only in the Sticky Note List
- No reminder support (sticky notes are for “recording,” not “executing”)
- No repeat support
- Can be pinned and archived
- Archived notes can still be restored from the archive entry
Typical uses: Meeting notes, idea snippets, temporary reminders, shopping lists
State machine: 0 = Normal, 1 = Done, 2 = Deleted, 3 = Archived
Schedule
Section titled “Schedule”A task with a clear start and end time.
- Appears in both the Todo List and the Calendar / Schedule List
- Must set a start time and an end time
- Can set reminders
- Can be dragged on the calendar to adjust time (Windows only)
Typical uses: Meeting at 3 PM, fitness class at 10 AM Saturday
Countdown
Section titled “Countdown”A todo with a target date set.
- Appears in the Todo List, showing “X days left” or “X days overdue”
- Also appears in the Countdown List (designed specifically for this)
- Essentially a type of todo
Typical uses: Mom’s birthday in 18 days, Lhasa trip in 30 days, mortgage payment in 5 days
Relationship Between the Three Types
Section titled “Relationship Between the Three Types”Pure todo, schedule, and countdown are mutually exclusive — an item can be only one of these three types.
Create a todo ├── Set a reminder → still a todo ├── Set a target date → becomes a countdown └── Set start + end time → becomes a schedule (also appears on calendar)Repeat todos are managed through a separate management interface, not during creation. Before triggering, repeat rules are only shown as previews on the calendar list and do not appear elsewhere. See: Repeat Todo Guide.
Sticky Notes are an independent data type, parallel to the todo system. Sticky notes do not support reminders or repeats, and do not appear on the calendar.
What is a List
Section titled “What is a List”A List is a collection container for todos / sticky notes.
- One account can create multiple todo lists and multiple sticky note lists
- Each list can set tag filter rules to only show items with specific tags
- A desktop widget binds to a list — the widget displays the content of that list
