UI Suggestion :

1. Collapsible Categories: Implement collapsible functionality for categories, allowing users to expand or collapse each category for better navigation and space management.

2. Collapsible Left-Hand Menu: Update the left-hand menu to include a collapsible feature that reduces it to icons when collapsed, making more screen space available while retaining quick access to key sections.

3. Dark Mode Toggle Update: Change the Dark Mode toggle to a button-style interface, as shown in the attached image, for a more intuitive user experience and consistent design.
