I have installed central phpmyadmin interface for all users under subdomain of my site. Now, I would like to provide a direct link to it for my webmins users. Is it possible to add custom links to Webmin's interface?
Are you using just Webmin, or are you using Virtualmin on top of Webmin? If you're using Virtualmin, you can add a custom link by going into System Customization -> Custom Links.
Please correct me if I am wrong but isn't that feature only available in the pro version of Virtualmin?
Yeah, it's possible the Custom Links are Pro-only... I sometimes lose track of which features are just in the Pro version. If you don't have a System Customization -> Custom Links, than it's likely Pro-only.
