I recently developed a WordPress plugin for Cage Cricket to integrate it’s mobile app with the website. One of the features I used in the plugin was customising the Admin Bar / Toolbar to add in custom images and links. The WordPress hooks make is relatively easy to customise the toolbar to achieve what you want.
To start off, you first need to create your plugin file and add in any hooks and functions. The below template tells WordPress to load any custom menu functions using the

remove_node() function, and passing in the node ID. Adding a new node is just as easy, using the
add_node() function and passing in a list of parameters. Documentation on adding nodes can be found here. Examples of both are shown below:
