Boostnote is an Electron app so it's based on Chromium; developers can use `Developer Tools` just like Google Chrome.

You can toggle the `Developer Tools` like this:

When errors occur, the error messages are displayed at the `console`.

## Debugging
For example, you can use the `debugger` to set a breakpoint in the code like this:

This is just an illustrative example, you should find a way to debug which fits your style.
