Hi there, for your first point, the Mobile Friendly setting of the Bipolar Matrix doesn't display the labels. TomG recommends in the below thread to disable this setting for the question and include text to mobile users recommending they rotate their device to landscape. He also has a formatting script that you might consider.

For your second and third points, I think you would be able to display this to the respondent using the Rich Content Editor. In the Rich Content Editor, add the below to the HTML/Source view by clicking the "<>" icon:

This will put your additional labels on the same line. Then, include a picture of a left/right arrow using the "Insert Graphic" icon.
You can also add some formatting to the Question Text container so that it is smaller and centered over the scale points. Adding the below to the question's JavaScript looked okay to me:
jQuery(".QuestionText , .QuestionBody").css("padding","0px");

jQuery(".QuestionText").css({
"max-width":"60%",
"margin":"auto",
"text-align":"center",
"padding-left:5%"
});

In addition to the mobile bipolar function Tom_1842 mentioned above I also have a bipolar/AHP slider function that converts a slider question into a bipolar or AHP slider question.
