runTimers Chrome 插件, crx 扩展下载

                    
Run multiple timers in a single browser tab
• Each timer can be a progress timer or a countdown timer.

• You can create countdown timers by setting either their durations (the length of time to count down from) or their end times.

• You can add a countdown timer to your Google Calendar by clicking on the timer's end time button. The button appears in either the Post time or Remaining time column.

• Your timer data is kept only in your browser's local storage — rather than on some server.

• The extension needs permission to your "tabs" so that it can avoid opening multiple runTimers tabs.

• You can format a timer's description by selecting its text and pressing Ctrl+B, Ctrl+I or Ctrl+U.

• Unless disabled in "Optional settings," runTimers will play a sound and show a desktop notification when a countdown timer ends. The runTimers tab must be opened in your browser — though the tab need not be active. By default, desktop notifications will remain open until you click on them.

• You can use the Targeting tool to create a countdown timer whose duration is a projection of the length of time needed to attain a target level (at a constant hourly earn/growth rate, and net of any current level).
