Sticky notes

Sticky notes are small colored plain-text boxes that float over the desktop, in the style of the Windows Sticky Notes app. From the tray menu: New sticky note (Ctrl+Alt+S, a global shortcut) creates a box; Show sticky notes (Ctrl+Alt+H) shows or hides them all at once. Each note has a + to create another and a ☰ menu to change the color, Send to today's note (writes the text as a bullet in today's note and discards the box) or Delete. Drag the header to move and the corner grip to resize. Notes are saved automatically and reappear when you reopen LightNote.

Checklist. The list button in the header (next to the +) turns the cursor's line — or the selected lines — into items with a checkbox, and undoes it on a second click. You can also type [ ] and a space at the start of a line ([x] creates the item already checked). Click the checkbox, or press Ctrl+Shift+Enter, to check and uncheck it: a completed item is struck through. Enter creates the next item; Enter on an empty item, or Backspace at its start, goes back to plain text. Remove completed items, in the note's menu, deletes the checked ones at once (Ctrl+Z undoes it). Items are saved as Markdown tasks (- [ ] item), so Send to today's note carries each one as a task.
