    Thanks for the great suggestion! We'll update the badge to show hours + minutes (e.g., 1h45) in the next version 0.2.3 to make longer timers clearer. Appreciate the feedback — it'll be live soon!

    The best countdown timer I've found, and I searched high and low for it. Simple, highly configurable, I use it daily. The only drawback is that if the screen turns off, it doesn't wake up to alert you that the time is up. Thank you for your work. I'm not talking about putting the PC to sleep, but just turning off the screen. My PC never goes into sleep mode. I've tested other countdown timers that do.
