When a custom toolbar with multiple buttons is configured in the Scheduler, the Today button may be automatically hidden due to the toolbar’s responsive behavior. While this behavior improves usability on smaller screens, it can also hide important actions from custom toolbars.

Consider adding a toolbar option that allows developers to disable responsive item hiding for specific custom toolbars, ensuring that all configured buttons remain visible.
