As you start out with your Electron app, you'll start to notice some features which have been carried directly across from the browser realm but make less sense for a desktop app. Here are the ones I can remember:

Ctrl or ⌘ + Click Opens Links in New Window

In Electron just like in Chrome, if you hold down the Ctrl key (or ⌘ on Mac) while clicking a link it opens in a new window. For many SPA apps, this is undesired and will load another full copy of your app in another window. You can disable this by calling the following code once you've created a BrowserWindow

win = new BrowserWindow({ ... });

An UI has several parts:

1. The "Layout": Defines the space each control takes. "This button is 32x32 px and is located in 100,100"
2. The "Function": what happens when a control is used. "This needs to happen when this button is pressed"
3. The "Skin": how each control is displayed. "This button, with this state, is a red circle"
4. Bells and whistles: Things like state animations, or playing a sound when a button is hovered.
5. Current focus.
6. A way to handle input: Move focus to next item. "There is a pointer pressing on this position".

Assuming you received the certificate in DER form, saved to cert.der:

openssl x509 -inform der -in cert.der -out chain.pem

Append the content of https://letsencrypt.org/certs/lets-encrypt-x1-cross-signed.pem.txt to chain.pem.
