It would be pretty cool if you could create a recurring countdown.
The use case here is something like an automated build system that masters the product a couple of times a week on a schedule. This would be nice to serve as a reminder of how much time you have before the next master if you wanted to get your changes into the next master. Or maybe it can track the time remaining till the next beer o’clock or something.
The basic idea is you create a schedule of “events”. The countdown counts down to the next occurrence of the event. Once that passes, the countdown restarts counting to the next occurrence.
