Start Tor Using User Specified Ports (like 80,443 by default in TB for example)
Once connected to the Internet, you are given two options in a pop-up box to connect to Tor, with the first option also offering the option to use Tor Bridges.
Missing, however, is the important power of allowing a third choice, that being, like in standalone Tor Browser, the ability for the user to connect to Tor using user specified ports. Ports 80,443 are the default in TB but can be changed.
I believe adding this third option would be a great strength for Tails.
