I can do the same on emacs too, says nothing about electron, just that you are familiar with css/js.

You can do the same with emacs because it's hackable enough, but you probably can't do the same with other native non-hackable apps like Word or Photoshop. I could do the same almost as easily with any Electron app, kind of like you can customize any website on your browser.
There are definitely awful Electron apps, but that's usually because of the developers, not because of Electron.
