How do i add a custom tab to the admin dashboard. I recently installed roundcube and I would like to use that as the default webmail for myself and my clients but I cant seem to add a new panel or custom panel to the dashboard. or how could I change the webmail access to the link that I have installed roundcube on.
Also I have been trying to add softalicious on a different one click instaler to the panel of the websites. How do I do this on my ubuntu 20 VPS. Please help I am near completion with my project and almost ready for production
