AsideNotes от Jarek "Tyler" M.

AsideNotes is a lightweight notepad and task planner that lives in the Firefox sidebar — always one keystroke away, and completely offline.

Write rich-text notes with a slash menu, inline Markdown, checklists, callouts and code blocks. Turn any note into a task with a due date, time, reminder and recurrence (daily, weekly, monthly, yearly or custom days). Capture instantly from the toolbar: type "!Call Ann tomorrow 15:00" and it becomes a scheduled task.

Organise with colored tags, search, and focus and zen modes. Deleted notes stay recoverable for 30 days. Copy any note as Markdown, or export everything to JSON.
