At the moment I can only see a green wfi icon which indicates that I am connected via wifi. In the settings connect via tor is on "When using wifi and mobile data", however the user has no way to see whether this is correct or not. It is possible just assuming that it is working, which is something that should be clear. If you look at ricochet messenger you can see what's going on with tor (connection,tor version etc.) this would be a great improvement I think.
