Resolved Bug #390
There are many usability issues regarded to the button to join the audio conference. The label of the button is wrong when the user is already in the audio conference, and the icon is very confusing.
Now, the label and icon is right.
The label of the button didn't change when you were streaming video. Now the label is right and you can stop sharing video clicking on the button.
