Hello @Maurizio_Vaggi, Thank you for getting in touch about this! I understand that being able to customize the toolbar position of UI3 would be convenient for you.

Unfortunately, it’s not possible at the moment.

However, this would be a fantastic feature request. I have seen similar feature requests from other community members here. Please take a look at this post when you have a moment and feel free to comment or vote on it.

Thank you once again for reaching out!
