This would require a great deal of forwarding to be done in the apache configuration. It is something that I have indeed put a tremendous amount of thought towards, however, some applications are independent of the process that you or I would prefer. Some applications can have SSL enabled from their own internal settings and some are not SSL enabled by how they deliver on ports other than 443.
I will look into this, however, this is something that we would need a great many of these applications very own authors to address... not QuickBox. This statement does not rule out however the ability to forward ports, and it is something that I have in the roadmap... however, there is no eta on this process.
Now, in regards to displaying port info etc ... I think this would be a nice feature to display (maybe under the user dropdown even ) on the dashboard.
