Hello Mike,

1) Since Revolution Slider is a 3rd party plugin, regretfully, we have limited support for it that only covers its compatibility issues with our themes.

So any question related to transitions, responsiveness, animations or how the certain feature works, would be getting outside the support loop we can offer.

You may refer to Revolution Slider online documentation:
http://revolution.themepunch.com/documentation/

Or try to contact them over plugin author dashboard for more general questions.

I can suggest that you read through this helpful tutorial, perhaps you can find what you need there:

2) You could probably do that through your page editor. All of these elements are added in WPBakery rows with some WPBakery shortcodes/elements. You'd just have find the row with element you'd like to hide, and in Row Settings go and tick Disable row option:

Or if you don't plan on displaying it again, you could just remove it.

3) Footer is made of few widget areas in which you can add different widgets you'd like to display.

So in order to edit footer's content, you'll need to edit these widgets.

You can read more about this topic in the following article:

Let us know if you need any further help.

Best regards!
