Hi,

Yes, the user interface in Odoo can be customized without using Odoo Studio, using the developer tools available in the Odoo UI. One common approach for making changes to views is by creating an inherited view from the user interface and applying the needed modifications.

To customize a view without Odoo Studio, you can follow these steps:

1. Navigate to Settings > Technical > Views in your Odoo instance.
2. Locate the view you want to customize. Views in Odoo define the structure and presentation of different parts of the user interface, such as forms, lists, and kanban views.
3. Once you've identified the view you want to customize, you can create an inherited view. This allows you to make changes to the existing view without modifying the original definition.
4. To create an inherited view, click on the Create button and select the appropriate view type (e.g., Form, Tree, Kanban).
5. In the inherited view, you can make the necessary modifications using XML markup. This might include adding, removing, or modifying fields, buttons, or other UI elements.
6. After making your changes, you can save the inherited view. Odoo will automatically apply your customizations and use the inherited view whenever the original view is rendered.

Hope it helps
