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).

I use it for Elvenar (video game). I would like to be able to display only the columns that are really useful to me (Item and remaining time). A dark mode would also be nice. However, it's a simple, handy and powerful tool.

Very good extension which does exactly do what I need. It functions without any flaws and very sophisticated. I have one suggestion for the design. It would be great if you could add a ta dark mode as well. I helped myself by changing the css with some effort and I thing that other users would appreciate a simple button to do the job.

Customizable. Unlike the dumb countdown extensions out there....
