Fast logbook is a free Chrome add-on developed by hidao80 that allows users to easily record and tally their work hours. With this program, users can save their work hours to a file and choose from various formats for aggregating and reporting their time.

Users have the flexibility to record time using both free text and keyboard shortcuts. The recorded working hours can be aggregated in HTML tables, plain text, or Markdown tables. Fast logbook also provides the option to download reports that include working hours and labor hours.

The program offers customizable task names corresponding to keys 1-9, allowing users to assign specific tasks to each key. Tags starting with "^" are not aggregated, while strings after ";" are included in the group of strings before ";" for aggregation. Users can also specify the unit for rounding the working time in minutes.

Fast logbook provides a convenient time recording popup that can be accessed from the menu or through keyboard shortcuts. In addition to the shortcut keys 1-9, users can enter free text in the shortcut key 0 field to record irregular tasks with timestamps. The recorded time and task content can be edited later, providing flexibility for corrections.

Overall, Fast logbook is a useful tool for individuals who need to track and manage their work hours efficiently. It offers a range of features and customizable options, making it a valuable addition to any workflow.
