[Lissy93]

Category: Feature

Overview: Adds an optional attribute, pageInfo.logo, enabling the user to display a logo image in the apps header.

Issue Number #104

New Vars

• pageInfo.logo - string - Optional
  • The path to an image to display in the header (to the right of the title). This can be either local, where / is the root of ./public, or any remote image, such as https://i.ibb.co/yhbt6CY/dashy.png. It's recommended to scale your image down, so that it doesn't impact load times
