Virtualmin's comparatively new File Manager module is really good one, so we don't want any other types of file managers on our servers and have removed the Webmin's Java File Manager module. Unfortunately, deleting the module does not take care of the relevant menu link, which I am afraid is hard-coded and still there. Clicking on it naturally shows
Error - File not found message.
So this request is about removing the hard-coded link for Java File Manager module from Virtualmin's UI, but at the same time (not to file another request) is about making ALL menu items dependent on whether their respective modules are presented in the system and enabled or not. Just think: why Webmin/Virtualmin would have menu items on UI if the respective modules are removed?!
