[Feature Request]: Please add public API for adding sidebar buttons and drawer widgets

What would your feature do ?

The sidebar in the new UI is great! As a plugin developer, it would be extremely useful to be able to add custom buttons and widgets that go in the drawer when the button is clicked, similar to how we can add items to the settings element with 'app.menu.settingsGroup'.

As a bonus, it would be fantastic from a user perspective to be able to enable/disable sidebar buttons just like being able to enable/disable extensions.

Proposed workflow

1. Call 'app.menu.sidebar.registerButton()'
2. Pass in parameters 'name' (string), 'buttonImagePath' (string, image path) and 'onRequestDrawerWidget' (function)
3. The app script would then add a new button to the sidebar (if not disabled by name in settings) and when clicked will call
   onRequestDrawerWidget to get the widget to be shown in the drawer, then open the drawer to show the widget.

Are you referring to the existing app.extensionManager.registerSidebarTab to register tab "buttons" in the sidebar, or do you mean something else?
