Hello,

1. Enter the page and set margin-top:-40px in the upper row settings: http://prntscr.com/lexqqs

2 Yes, it is possible by means of HTML blocks and columns visibility https://xtemos.com/docs/woodmart/html-blocks-2/#main_footer and https://wpbakery.com/video-academy/control-elements-different-devices-responsive-column-controls/ you will need to set up one column footer layout https://xtemos.com/docs/woodmart/set-up-footer/

3.
a. Add this code to the Theme Settings > Custom CSS > Global

body img {
	pointer-events: none;
}

If it does not work, provide pages URL where it should be removed I will provide more precise code.

b. There is no option for that, unfortunately.

4. We provide the Revolution Slider because some users prefer more functionality which provides Slider Revolution, you can delete it if you do not need.

5. I do not see any bugs here, this is the issue of configuration http://prntscr.com/mm0ymi and http://prntscr.com/mm0yzz you will find the option to set the custom size.

Compare and set equal paddings in the columns https://gyazo.com/739563025a065d0bd083dd2ec64f25ff
