Turn long break into short break.

Sometimes you only need a short break and 15 minutes is too long. Maybe an option to turn a long break into a short break could be useful.

I believe it's already possible to do that.
Click on the gear icon, than, click on preferences. You will be prompted with a
window where you'll be able to set your own custom config.

I was thinking more about turning a particular break to a short break in the moment. But I hadn't realised about those global options, thanks!
