This is an electron application, it's all in javascript. If you're building a big feature, it's a really good idea to create an issue and discuss is to make sure that the maintainers will actually want to include the feature.

If you're building a UI component, you'll want to run npm run storybook and create an index.story.js and/or an individual story for the component. There are plenty of examples how to do this in this repository and in react-storybook.

• Make sure you run npm run start AND npm run start:desktop:dev. It's much faster to develop than building each time
