notetask

Notetask is a cross-platform application for managing task lists that include completion status, task description, and notes. Each task can have a due date and be marked as a favorite with a star. It uses its own storage text format based on Markdown.
It is designed to help you quickly organize a large number of small routine tasks. You can enter tasks directly in the app or paste raw text from the clipboard — such as a list of requirements or ideas — then sort them into groups, set durations or amounts, and start working right away. Perfect for managing project to-dos, bug lists, feature requests, and other ongoing tasks.
