Here is a list of things that will help get it across the finish line: - Run npm run lint locally to catch formatting errors earlier. - Include tests when adding/changing behavior. - Include screenshots and animated GIFs whenever possible. - If you added new translation strings ensure that you have added empty strings for all languages - If you added new functionality or modified existing functionality please ensure it is tested

Would it be possible to have an option for a sleep timer? Something you can set either by timer or by time of day (i.e. 15 mins or 10:00pm.) It would also be nice if there was an option for a fade out so when the music fades, it's not a hard cut, but instead a nice fade (in which you can set the duration.)

Features still missing from branch:

• Timer for seconds/minutes/hours
• Add the fade duration

Will update the branch once I have added/tested the above features.

Added seconds, minutes and hours inputs. Thought adding a fade duration wasn't really necessary so didn't include it in the PR.

Details in regards to the changes. I changed the props in AlarmModal to states as they better handled UI updates such as clearing the time set when a duration value was changed, or, clearing the duration value when a time was set.

I also modified the time and duration settings to be updated on save of the alarm modal. This will prevent the alarm triggering on change of the seconds duration, waiting for the user to press okay to confirm the time allowed. The scenario this would be most handy is if a user set a duration of a second or two. If the settings value was updated on change then the alarm would trigger instantly not allowing the user enough time to click 'ok' to confirm.

Dag yo, this feature would be awesome! I'm surprised the PR's been sitting here so long.
(Just discovered this project myself. Great stuff guys!)
