How to use “Toggle Full Width” option for a specific user?

Hi everyone,

I want to enable the “Toggle Full Width” option only for a specific user in my Frappe/ERPNext instance.
Is there a way to apply full-width view based on a user, role, or permission?

For example, I want one user to always see the form in full width, while others should see the normal default width.

Has anyone implemented this using user settings, custom scripts, or role-based permissions?
Any guidance or best practice will be helpful.

Thanks!

Since this is a per user setting, I’m curious why you’d need to intervene. Are users sharing logins (causing shared user to have to switch back and forth)? Why not leave it up to the users?
