Description:
Many new users trying LibreOffice find the interface unfamiliar compared to Microsoft Office and often return to MS Office despite LibreOffice offering equivalent functionality.

LibreOffice already includes several UI layouts (Classic, Tabbed, Compact Tabbed, etc.), but the Tabbed UI—which closely resembles the Microsoft Office Ribbon—is not the default and is not clearly presented to new users. As a result, users may not discover it.



Steps to Reproduce:
1. Install LibreOffice.
2. Launch it for the first time.
3. The application starts with the Classic toolbar interface without any prompt to choose a preferred UI.

Actual Results:
Users see only the Classic interface and may assume no Ribbon-like option exists.

Expected Results:
At first startup, LibreOffice should offer a simple dialog allowing the user to choose between available interface styles, e.g.:
- Standard (Classic toolbar)
- Tabbed (Ribbon-like)
- ..
This choice should include small preview images and an explanation that it can be changed later via View → User Interface.


Reproducible: Always


User Profile Reset: No

Additional Info:
Benefits:
- Improves onboarding and usability for new users.
- Reduces interface-related friction when switching from Microsoft Office.
- Promotes awareness of LibreOffice’s modern UI options.

Additional Info:
This change would not alter functionality or remove any interface options, but simply make the user aware of them earlier, avoiding that by finding Libreoffice's layout very different from the current Microsoft Office's they may decide to get back to it.
