Some Odoo modules create new applications, and others add features or modify existing applications. While the technical components involved are about the same, an app is expected to include a few characteristic elements. Since we are creating a new library app, we should include them in our module.
An app should have:
- An icon, to be presented in the app list.
- A top-level menu item, under which all the app's menu items will be placed.
- Security groups for the app, so that it can be enabled only for users that need it, and where access security will be set.
To add an icon, we just need to place an icon.png file in the module's static/description/ subdirectory. This was done in the Adding an icon section.
Next, we will take care of the app's top-level menu.
